SB = $30 each
PB = $50 each

given - 30x + 50y = 1100 , where x is number of SB and y is number of PB
also given 25<= x+y <30, consider it as "T" i.e. x+y=T

Ymin and Ymax are required

from eq 1 = 30 (T-y) + 50y = 1100
30T + 20y = 1100
y = 55 - (3T/2)

for Y to be count, T should be even

for Ymax, T should be minimum possible even value = 26
and Ymin, T should be maximum possible even value = 28

Ymin becomes - 13 (after substitution)
and Ymax becomes - 16

Let's say X standard baskets and Y premium baskets are purchased.
3X + 5H = 110
Above is the Diaphontine Eqn,
Max value of H is 22 and the minimum value is 1.

i am going with min as 10 and max as 15.
we are given, 30s+50p=1100 which is 3s+5p=110 and between 25 and 30 s+p should be
testing out numbers given in the option, only 10,13 and 16 satisfies hence out of these three 10 is min and 16 is max.
p.s - calculation for one option number -
if p is 10, 3s+5x10=110 = 3s = 60, s = 20 and s+p = 30 valid as between 25 and 30 inclusive.

Maximum premium: she can buy all 22 premium for total of 50*22=$1100 but she has to buy combination of standard & premium.
if she buys 20 premium, she will be left with money, since she must spent all hence this is not correct.
she can buy 16 premium and use all of rest of money for standard with no money leftover.

Minimum premium: she can buy 1 premium for $50 & use all rest of money to buy standard with no leftover.

Answer: Max: 16, Min = 1

Given: S=30$, P=50$

25<=S+P<30
Budget =1100$
Total no. =T=S+P can be 25,26,27,28,29

find Min S and max P

Imagine all are P =1100/50=22, i.e s=0 so this is not possible but start with this

with only 2less there is only 100 fiff and 3 gain in s , since S=30$ so t=23 so this is not possible

With P (max possible)=16 we have 800$ spent and 300 sent for 10 in S so Smin=10

A corporate event planner is purchasing gift baskets for an upcoming gala. She will purchase a combination of standard baskets, which cost $30 each, and premium baskets, which cost $50 each. Her total budget for the gift baskets is exactly $1,100, all of which must be spent on these two items. To ensure every VIP receives a basket without overstocking the display tables, the total number of baskets purchased (standard and premium combined) must be at least 25 but no more than 30.

In the table below, identify the Minimum possible number of premium baskets the planner could purchase, and the Maximum possible number of premium baskets the planner could purchase. Make only two selections, one in each column.


let premium basket be x and standard be y
we know
50x+30y =1100
25>=x+y<=30

check with given values of x
at x= 1 we get y = 35 ; not valid option

at x = 10 , y is 20
50*10+ 30*20 = 1100
at x= 13
1100- (50*13) = 30*y
y= 15

at x= 16
1100-( 50*16 ) = 30*y
y=10

at x = 20
1100- (50*20) = 30*y
not valid as its not meeting condition

minimum value of premium will be 10 and maximum is 16
10 & 16 is correct option

1100 = 30s + 50p
110 - 3s =5p (Note that s has to be divisible by 5)
Listing out the options give us

10

s51520
p19161314

And adhering to the constraint that s+p should lie between 25 and 30. ie 30 > s+p > 25

we have the values of p as 13 and 16

In the table below, identify the Minimum possible number of premium baskets the planner could purchase, and the Maximum possible number of premium baskets the planner could purchase. Make only two selections, one in each column.

Given cost of 1 standard = $30
Cost of 1 premium = $ 50
Now lets assume no. Of standard = S and no. Of premium = P

We have been given additionally that 30*S + 50*P = $ 1100
And a condition that maximum value of S+P = 30
and minimum value of S+P = 25

now we can use trial and error method to determine what could be the max and minimum value of P
by doing the trial and error method for max value of P we can have max value of P as 10 so 30 - 10 =20 for S
Therefore making 30*20 + 50*10 =1,100

A corporate event planner is purchasing gift baskets for an upcoming gala.
She will purchase a combination of standard basket, which cost $30 each, and premium baskets, which cost $50 each.
Her total budget is exactly $1100.
25 < Total number of baskets purchased < 30

Let the number of standard and premium baskets purchased be x & y respectively

30x + 50y = 1100
3x + 5y = 110
y = (110 -3x)/5

25 <= x+y = x + (110-3x)/5 = (110 + 2x)/5 <= 30
125 <= 110 + 2x <= 150
15 <= 2x <= 40
7.5 <= x <= 20

For y to be an integer, x should be a multiple of 5
x = 10; y = (110-30)/5 = 16
x = 15; y = (110-45)/5 = 13
x = 20; y = (110-60)/5 = 10

Min y = 10
Max y = 16

Given: 30S+50P=1100 and 25=<S+P=<30

Minimum:
If P=1, then 30S=1050; S=35 ; S+P=36......No
If P=10, then 30S=600; S=20 ; S+P=30 ..... Correct

Maximum:
If P=20, then 30S=100..... No
If P=16, then 30S=300 ; S=10 ; S+P+26......Correct

From the given information, 30x + 50y = 1100. This is basically 3x + 5y =110.

And, 30 ≥ x + y ≥ 25. We have to minimise and maximise premium baskets. I did it via trial and error method which is why it took me sometime.

To minimise y, x needs to be maximised. I used y = 1 here to try out but that means 3x + 5 = 110. Which means x = 35 which is not possible as x+ y max can be 30. So next y =10 gives, 3x +50 = 110. So, x = 20. And total x+y=30. This works. Hence y(min) = 10.

Similarly, in order to maximise y, we need to minimise x. We know = 22, 20 clearly won't work. So y=16 gives 3x + 80 = 110. Which means x = 10. Here, x + y is 26. This also works as per given constraints. So y(max) = 16.

Hence 10 and 16 are the answers.

standard basket - s, premium basket - p. Total cost = 1100.
30s + 50p = 1100
total items: 30 >= s+p >= 25
subsituting values available, min premium 10, max premium 16 to meet above equation.

From the given options.
If Min 1 basket for 50 is chosen the total baskets shoot up to 36. Does not satisfies the condition. (1100-50 =1,050 & 1050/30=35)
With next best minimum option i.e. 10, total baskets come up to 30. Just hits the mark. (50 * 10 =500, 1100- 500 =600, 600/30=20)
Similarly, tried the max possible choices and 16 fits the bill. ( 50 * 16=800, 1100-800 =300, 300/30=10 so total number is 26)

In the table below, identify the Minimum possible number of premium baskets the planner could purchase, and the Maximum possible number of premium baskets the planner could purchase. Make only two selections, one in each column.
I got it wrong at the first but realised later. The best method would be to use substitution method.
The two equations would be 30S+50P=1100 and 25<_ S+P<30
So the minimum possible when you substitute 10 you would spend 500 on P leaving you with 600 to spend on S. But when you do that you would have got 20 and 10 baskets for S and P which would voilate the less than 30 baskets condition. So when you substitute 13 you will get it right for minimum P.
In the same way when you do it for maximum P you would get it wrong when you substitute 22 for P leaving you with no Baskets for S and total number of baskets being 22 which voilates atleast 25 baskets condition. Substitute 20 you will get it right.
So 13 and 20 would be the answers.
If you like the solution Please don't forget to give the kudos,thanks!

let s = no. of standard baskets
p = no. of premium baskets

30s+50p =1100
3s+5p = 110

and 24<s+p<31

3S = 110 - 5P
For S to be an integer, 110 - 5P must be a multiple of 3.

Answer: Min: 10, Max: 16
x = quantity of standard baskets, y = quantity of premium baskets
30x + 50y = 1100
25 <= x+y <= 30
From the info in the passage, we use the minimum and maximum total number of baskets to get two equations we can plug in for x and solve for y.

Max: 30*(25-y) + 50y = 1100, y = 17.5
-> We can't have half a basket, so we take 17 and test it -> 30x + 50(17) = 1100, x = 25/3, not possible, so we try 16 -> 30x + 50(16) = 1100, x = 10 -> works!

Min: 30*(30-y) + 50y = 1100, y = 10
