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.
