Nina mixed 16 ounces of olive oil with vinegar to make salad dressing. How many cups of oil did Nina use? (1 cup = 8 ounces) A. 128 cups B. 8 cups C. 2 cups D. 1 cup

Nina used 2 cups. The correct answer is B. Use this formula;

lets assume y is the amount of ounces she used. Lets assume x is the amount of cups she used.

y = x (8)

Replace y with 16.

16 = x (8)

Divide by 8.

2 = x

Thus, 2 cups.

The answer is C. 2cups
