I want to make a mixture of feed that is 16% protein. I need a total of 2000 pounds, so I'm after 320# of protein.
I can mix soybean which is 48.5% and milo which is 9%. I'm not sure how to figure out the answer.

Soybean - 354.43 pounds
Milo - 1645.57 pounds

Soybean 48.5% - x pounds
Milo 9% - y pounds
Total mix - 2000 pounds
Protein 16 %- 320 pounds
x+y=2000
0.485x+0.09y=320 -->
0.485x+(2000-x)*0.09=320 -->
x=354.43 pounds & y=2000-354.43=1645.57 pounds

Camp Pineveiw's cook, Margaret Johnson, was just about to begin preparing the picnic lunch for all the campers. She already knew she needed to fill 55 bowls of the same size and capacity with the same amount of food. When she was done, she decided to read the guidelines for the picnic, just out of curiosity. The guidelines said:

1. Every camper gets their own bowl of soup.
2. Every two campers will get one bowl of spaghetti to share.
3. Every three campers will get one bowl of salad to share.
4. All campers are required to have their own helping of salad, spaghetti, and soup.

After some rapid calculations, Margaret was able to figure out how many campers were going to the picnic. Can you?
