Our Problem: We have 200 PPL "Think Energy" kits that need to be returned to PPL. The kits look like this:



The cafeteria has boxes that we can use for free to pack up the kits. The available boxes come in two sizes:

Also, United States Postal Service regulations state that we cannot ship these boxes without covering the markings. (See Below)

As a result of these requirements, we will need to buy brown shipping paper to wrap each box.

**We found in class that the smaller box can fit up to 6 PPL boxes in it and the larger box can fit up to 11 PPL boxes in it.**
You need to find: 1. How many boxes (the least amount possible) do we need if we use the first size? 2. How many boxes (the least amount possible) do we need if we use the second size?
 * We found that we would need 19 boxes to ship all the PPL boxes.**
 * 34 boxes.**

3. How many rolls of brown paper do we need to buy if we use box 1? Box 2? 4. How much will it cost to buy the paper and ship the boxes to Harrisburg for box 1? Box 2? 5. Which boxes offer the cheaper option?
 * Notes - We wrapped each box in paper and found that we'd need about 2,718 sq. in. of paper to wrap the large box and 2,106 sq. in. of paper to wrap the smaller box.**
 * Here are the deals that we found on paper. You need to figure out which roll is the best deal before answering #3-5 below.**
 * **Roll 1 - 300 ft x 36 inches - cost $10.99**
 * **Roll 2 - 1010 ft x 24 inches - cost $50.80**
 * **Roll 3 - 1050 ft x 18 inches - cost $23.04**
 * **Roll 4 - 30 ft x 30 inches - cost $0.96**

Before we start: 1. What information are we going to need? 2. Where or how are we going to get that information?
