Question

Mr. Porod's famouse peanut butter pie has 4 ingredients, peanut butter, cream cheese,powdered sugar and cool whip. The receipe call for 12ox of cool whip. Unfortunately cool whip is only sold containers of 8oz or 16oz.How much of the containers need to be added? Write and solve a proportion for both the 8oz container and 16oz containers.

Answer 1

To get 12 oz of Cool Whip, two 8 oz containers would be needed, using only 12 oz out of the total 16 oz. If using a 16 oz container, only one would be required with some leftover.

Step-by-step explanation:

The student needs to determine how many containers of Cool Whip are needed to get exactly 12 oz for Mr. Porod's famous peanut butter pie. Because Cool Whip only comes in 8 oz and 16 oz containers, we need to figure out the best way to combine these to get exactly 12 oz.

Using 8 oz containers:

Let x represent the number of 8 oz containers. To create a proportion, we compare the desired amount with the amount one container can provide:

8 oz/1 container = 12 oz/x containers

By cross-multiplying, we get:

8x = 12

Now, we solve for x:

x = 12/8

x = 1.5

Since you can't purchase half a container, we would need to buy two 8 oz containers and use only 12 oz out of the 16 oz total.

Using 16 oz containers:

Let y represent the number of 16 oz containers. Again, we set up a proportion:

16 oz/1 container = 12 oz/y containers

By solving the proportion, we find that y would be less than 1, which indicates that one 16 oz container is more than enough. Therefore, we would need just one 16 oz container and have some leftover.

Answer 2

If he buys the 12 oz container, he will add about 1 1/3 of those, and the 16 oz container about 3/4 of one.
