Answer:
4/3 servings or her dish can be made
These are the 2 equations:
Total = 5 and 1/8 pounds + 6 pounds + 4 and 7/8 pounds
N = Total / 10
Explanation:
We know 1 serving = 12 pounds
We want the number of servings able to make. call it N
N = (Total pounds)/ (12 pounds/serving)
P = pasta per serving
S = sauce per serving
O= onions per serving
It appears that
P*N = 5 and 1/8 pounds
S*N = 6 pounds
O*N = 4 and 7/8 pounds
5 and 1/8 + 6 + 4 and 7/8 = Total
16 pounds total.
N = 16/12 = 4/3 servings
Total = 5 and 1/8 pounds + 6 pounds + 4 and 7/8 pounds
N = Total / 10
