Hello! Can you please explain the calculations of Q1? Please correct me where I am wrong.

Renting a Car: 405*4 (flight tickets) + 25*4 (luggage) + 27*6+150 (Car rental +parking) = 2032

Using Public Transportation: 405*4 (flight tickets) + 25*2 (luggage) + 200 (Public tran)
=1870

Difference = 2032 - 1870 + 162

­The baggage cost is per non-stop flight and there are two such flights included in one round-trip so will have to add 25*2 (child seat), so will add up to 162+50=212.

­Hey I think there is no use of Airline Calculation in Question 1 as it talks about rental difference. If also we take the cost there is no mention of Child Safety seats. Kindly help as I am not getting the correct answer . getting 112

­Hi Satya, actually there is a mention of the child safety seats (1st tab-3rd paragraph) and we need to consider it as the cost of renting the safety seats would be higher than if the family carries it!
Hope this helps.

According to 'Trip plans' tab, line "While at their destination, they can use public transportation, which they estimate will cost a TOTAL of $200".
With the total charge of $200, adding child safety seat charges is not required.
In short, while using public transport, the family need not carry kids in child safety seats because the passage claims if and only if(not in public transport case) they rent a car, children require child safety seats.

Moreover,
1. if the family members take public transport, they need to pay for the flight tickets.
If the family members rent a car, they still need to pay for the flight tickets.
2. 3 suitcases also need to be paid for, in both cases.
Thus, flight tickets and suitcase charges will not contribute to the asked difference as they are common in both cases; calculation effort can be saved there.

[Note: line 'one to their destination and the other back home' indicates that child safety seats, if carried along on the trip, would then be carried back home as well. To carry the 2 child safety seats, while going on the trip, the family will pay 25x2. Similarly, when coming back the family again will pay 25x2. Thus, 25x4 is charged for only child safety seats and does not include any suitcase charge.]

Taking all this into account, your calculation can be re-framed as:
Renting a car:25*4 + 27*6 + 150 =$412
Using Public Transport: $200
Difference=$412-$200=$212 (Option C)­

In Q1, they are said to use flight option A5 which allows the first check-in item free. They have total 3 suitcases + 2 child safety seats and they are 4 people so surely one of the child safety seats will be the free checked in item for one person. Hence they have to only pay for 1 child safety seat. So even if counting for round trip and 2 child safety seats, shouldn't we go 25 * 2 and not 25 * 4?

Q1. Suitcases and flight tickets would not contribute to the difference asked. You can save effort on that unwarranted calculation.
1 free item on the round trip would be the mandatory suitcase which the Ramos family must carry while going on the trip and while coming back.
For optional child safety seats, the family would pay depending on their preferred mode of transportation.
Note: Baggage fees are per nonstop flight NOT per person.
Even then if you want to see through, here is the calculation.

While taking public transport:
Round-trip flight tickets cost per person= 405x4 = 1620
Going= (3 suitcases)0x1+25x2 = 50
Public Transport= 200
Coming back= (3 suitcases)0x1+25x2 = 50
---------------------------------------------------------------------
Total: $1,920
---------------------------------------------------------------------

While renting ONLY car:
Round-trip flight tickets cost per person= 405x4 = 1620
Going= (3 suitcases + 2 child safety seats = total 5 items to be carried) 0x1+25x4 = 100
(According to A5's policy, any 1 item for the family can be carried for free so 0x1+25x4.)
6 days car rent from C3 company=27x6=$162
Parking charge=$150

Coming back= (3 suitcases + 2 child safety seats = total 5 items to be carried) 0x1+25x4= 100
(According to A5's policy, any 1 item for the family can be carried for free so 0x1+25x4.)
-----------------------------------------------------------------------------------------------------
Total: $2,132
-----------------------------------------------------------------------------------------------------

Required difference= 2132-1920 = 212
The required difference is $212 (Option C)

PS: Post updated for clarity.

---------------------------------------------------------------------
Total: $3,540
---------------------------------------------------------------------

While renting ONLY car:
Going= (flight tickets)405x4 + (3 suitcases)0x1+25x2 + (2 child safety seats)25x2
6 days car rent from C3 company=27x6=$162
Parking charge=$150

Coming back= (flight tickets)405x4 + (3 suitcases)0x1+25x2 + (2 child safety seats)25x2
-----------------------------------------------------------------------------------------------------
Total: $3,752
-----------------------------------------------------------------------------------------------------

Required difference= 3752-3540 = 212
The required difference is $212 (Option C)

Referring to the last para of the first tab - "They plan to take a total of 3 suitcases on each of the nonstop flights, and each suitcase will be checked as a separate baggage item for each nonstop flight. If they take their own child safety seats, then each seat will be checked as a separate baggage item, and they will check a total of 5 baggage items on each flight."

I believe that in your calculation of While Renting Only car, the cost of one of the child safety seats should not be included IMO as it will be checked in as a free bag according to A5's policy (4 members are each allowed one free bag but they only have 3 suitcases, hence one child seat can be checked in for free)

Question 3 is pretty straightforward:

Assume the Ramos family plans to take their own child safety seats for their children. In accordance with the Ramos family's plans for their trip, for each of the following airlines, select Yes if the total baggage fee for using that airline would be greater than the total baggage fee for using Airline A1. Otherwise, select No.

  • They would have 5 luggage items. With airline 1, it is $125 total.
  • With airline 2, it is 30*3 = $90, so the answer is NO
  • With airline 3, it is $30*5=150, so the answer is YES
  • With airline 4, it is $25*5=125, so the answer is NO again because 125 is not greater than 125. This is the catch here.

­Q1. We need to calculate the difference between estimated costs if they use public transportation and if they rent ONLY a car.

While renting the car we need to decide whether to rent the child safety seats or to carry them with the flight baggage paying money for 2 additional baggage items.
It is mentioned that the family rents ONLY a car which means they are not renting child safety seats.
So they are carrying the seats with them. In this case according to 'Trip plans' tab, last line: If they take their own child safety seats, then they will check a total of 5 baggage items on each flight.
Airline Costs tab: A5 airline child safety seat baggage fee=$25x4=$100 [2 child safety seats will be carried while going on the trip and will be carried back home on A5 so, 25x4]
Based on the lowest daily car rental fees(excluding child safety seat charges), the family would pick company C2.
6 days car rent=27x6=$162
Parking charge=$150
Total car renting charge=$100+$162+$150=$412

Public transportation costs $200

The required difference=$412-$200=$212 (Option C)­

Can someone please help with the second one?
C1 cost should be 200 by multiplying 30 x 6 + 10 x 2.
C2 = 186
C3 = 210
C4 = 236

Where am I wrong here?

Assume the Ramos family plans to rent a car and child safety seats for their children. In accordance with the Ramos family's plans for their trip, for each of the following car rental companies, select Yes if the total daily rental fees for using that company are greater than the total daily rental fees for using Company C1. Otherwise, select No.

You’re mixing things up in two ways.

The question is about daily rental fees, so for C1 it should be
30 + 2*10 = 50 per day, not a 6-day total.

Even if you wanted the 6-day total, the seats are per day per seat, so C1 should be
6*30 + 6*2*10 = 180 + 120 = 300, not 30*6 + 10*2 = 200.
