5. an all-chocolate chessboard with white & dark chocolate chessmen (25 lb, $149.99), which requires refrigerated shippingWhizzo Chocolate Company uses only the following shipping methods:

Western Food Sender
a) WFS non-refrigerated service: $50 plus $10 times each pound
b) WFS refrigerated service: $80 plus $15 times each poundIf a single order is a “mixed order”, that is, it contains both items that require refrigerated shipping and items that do not require refrigerated shipping, it does no harm to the latter items to ship them in refrigerated shipping. If a single order is a mixed order, customer has a choice:

a) only items requiring refrigerated shipping sent via refrigerated shipping , and all other items sent without refrigeration

b) all items, regardless of type, sent via refrigerated shipping When a customer places a mixed order, the Whizzo sales representative will make this choice clear to the customer, and make clear that absolutely no damage will occur by refrigerating those items which don’t require refrigeration.

Suppose you have a mixed order and it is all going to be sent via refrigerated shipping. That cost $80 + $15*(# of pound). Suppose some items, not requiring refrigeration, are removed from that shipment, and a non-refrigerated shipment is created. The additional cost is the $50 base cost of a non-refrigerated shipment. The savings per pound is the difference in the per pound rates: $15/lb – $10/lb = $5/lb. When will this saving exceed the additional $50 cost? When the total weight of the non-refrigerated shipment exceeds 10 lbs.

The first order has five 12-piece assortments not requiring refrigerated shipping: 5 x 1.5 = 7.5 lbs of goods not requiring refrigerated shipping. That is not enough to justify a separate nonrefrigerated order.

1. If a person in Pennsylvania has a total of $500 to spend on a Whizzo order, which of the following orders could he afford, including the cost of shipping? 
 
 five 12-piece assortments, all requiring refrigerated shipping
 
 Price: 1.5 * 5 = 75 
 Shipping fee: 80 + 1.5 * 5 * 15 = 192.5 
 => Total less than $500   
 two large chocolate-covered fruit baskets
 
 Shipping fee: 80 + 15 * 30 * 2 = 980 > 500   
 the all-chocolate chessboard with white & dark chocolate chessmen
 
 Shipping fee: 80 + 15 * 25 = 455 
 Price: 155 
 ==> Total more than $500    
 2. For each of the following “mixed orders”, each containing twenty items total, which shipping option will be less expensive?

Option A) only items requiring refrigerated shipping sent via refrigerated shipping , and all other items sent without refrigeration
Option B) all items, regardless of type, sent via refrigerated shipping
 
 fifteen 12-piece assortments requiring refrigerated shipping and five 12-piece assortments not requiring refrigerated shipping
 
 Option A can reduce some cost for some pounds not requiring non-refrigerated shipping but incur the fixed cost for Non-Refrigatered shipping ($50) 
 whether to choose B is instead of A depends on whether the additional fee for refrigerating those which does not require refrigated shipping is less than $50  
 Except the fixed cost, the difference between the 2 Refrigerated and Non-Refrigerated shipping service is $5/per pound 
 5 (12 piece assortments) * 1.5 (lbs) * 5 ($ per pound) = 37.5 < 50 
 Option B is better   
 ten 12-piece assortments requiring refrigerated shipping and ten 12-pieceassortments not requiring refrigerated shipping
 
 Similar reasoning 
 10 (12 piece assortments) * 1.5 (lbs) * 5 ($ per pound) = 75 > 50 
 Option A is better   
 five 12-piece assortments requiring refrigerated shipping and fifteen 12-piece assortments not requiring refrigerated shipping
 
 If the number of those not requiring refrigerated shipping increase, the the additional fee for refrigerating those which does not require refrigated shipping will also increase  
 The additional fee for this case will be higher than that of the 2nd case ($75) and therefore higher than $50 
 Option A is better

Someone please explain Q2

Can someone explain why options 2&3 require refrigeration???
I thought only option 1 required refrigeration because of the words "all refrigerated".

DhanyaAbhirami · Answer

Glancing the options, all are n = 20 items are 12-piece assortments
Which means same weight for all items W (W = 1.5 lbs)
Which also means total item cost = C (C = 20*$14.99), don't have to worry about this component while comparing
If refrigerated, n product shipping cost = 80 + 15 * n * W
If not refrigerated, n product shipping cost = 50 + 10 * n * W
When all 20 items are refrigerated RF = 80 + 15 * 20 * W = 80 + 300 W = $530 = 130 + 266.67 W
When some are RF some are NRF, (80 + 15 * n * W) + (50 + 10 * (20-n) * W) = 130 + (200 + 5 * n) * W
fifteen 12-piece assortments requiring refrigerated shipping and five 12-piece assortments not requiring refrigerated shipping
RF + NRF = 130 + (200 + 5 * 15) * W = 130 + 275 W
RF + NRF > RF

ten 12-piece assortments requiring refrigerated shipping and ten 12-piece assortments not requiring refrigerated shipping
RF + NRF = 130 + (200 + 5 * 10) * W = 130 + 250 W
RF + NRF < RF

five 12-piece assortments requiring refrigerated shipping and fifteen 12-piece assortments not requiring refrigerated shipping
RF + NRF = 130 + (200 + 5 * 5) * W = 130 + 225 W
RF + NRF < RF

Question 2 required a lot of calculations and there were too many carefully crafted calculations. Even with a calculator, it takes a while to calculate and compare the two values. Does anyone have a time-efficient way to solve question 2? I made guesses looking at the numbers in the calculations without actually plugging in the values but with that, I got option 2 incorrect.

a) WFS non-refrigerated service: $50 plus $10 times each pound
b) WFS refrigerated service: $80 plus $15 times each pound

You don't need to think about  refrigerated shipping because it's fixed. You cannot ship chocolate requiring refrigerated shipping to non- refrigerated shipping service and since every option including refrigerated shipping, $80 starting cost is already happened.
You should not add another $80.

So problem we left is 5/10/15 12-piece assortments (1.5 lbs for each one)

which means 7.5lbs / 15lbs / 22.5lbs

first, let's just try 10lbs.  nonR = 50+10*10 = 150 // R = 150 . It's same. 
 Meaning  we must choose nonR when it's heavier than 10lbs  
  also, we must choose R when it's lighter than 10lbs
 
7.5lbs - lighter than 10lbs. no need to calculate. -> choose R 
15lbs - heavier than 10lbs. no need to calculate. -> choose nonR 
22.5lbs - heavier than 10lbs. no need to calculate. -> choose nonR

Bunuel · Answer

Say N is the number of nonrefrigerated boxes.

Since there are 20 boxes in total in each statement, the refrigerated boxes are (20 - N). The cost to ship those refrigerated boxes is 80 + 15 * (20 - N) * 1.5, and it is the same in both options, so we ignore it. We only compare the nonrefrigerated part, which weighs N * 1.5.

In Option A, that weight ships nonrefrigerated: 50 + 10 * (N * 1.5).
 In Option B, it ships refrigerated: 15 * (N * 1.5).

At N * 1.5 = 10 both cost 150.
 If N * 1.5 < 10 choose B.
 If N * 1.5 > 10 choose A.

Row 1: N = 5, weight = 5 * 1.5 = 7.5 so B
 Row 2: N = 10, weight = 10 * 1.5 = 15 so A
 Row 3: N = 15, weight = 15 * 1.5 = 22.5 so A

Answer: B, A, A
