Question

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

Answer 1

The answer is C.2cups

Answer 2

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.
