Chef Selena is making her special dish that requires pasta, sauce, and onions.
She has 5 1/8 pounds of pasta, 6 pounds of sauce, and 47/8 pounds of onions.
How many servings of her dish can she make if each serving is 12 pounds?
Which two equations are needed to solve the problem?

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

Step-by-step 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

answer: 0.64
