Question 31 • *MHS - Algebra 1 - S1 - CR

A snack tray at a party has cheese squares with 2 grams of protein apiece and turkey slices with 3 grams of protein apiece. Which inequality represents the possible ways Nina can eat 12 or more grams of protein, if x is the number of cheese squares that she eats and y is the number of turkey slices that she eats?

Answer

A

12 ≤ x + y

B

12 ≥ x + y

C

12 ≤ 2x + 3y

D

12 ≥ 2x + 3y

Explanation

Each cheese square contributes 2 grams of protein, so x squares provide 2x grams. Each turkey slice contributes 3 grams, so y slices provide 3y grams. Eating 12 or more grams means the total, 2x + 3y, must be at least 12; this is 12 ≤ 2x + 3y, choice C.
