SAT Math Multiple Choice Practice Question 463: Answer and Explanation
4. Six cups of flour are required to make a batch of cookies. How many cups of flour are required to make enough cookies to fill 12 cookie jars, if each cookie jar holds 1.5 batches?
Correct Answer: A
A You need to take this question one step at a time. First, figure out how many batches there are in 12 jars of cookies. If one jar holds 1.5 batches, then 12 jars will hold 12 × 1.5, or 18 batches. Now you need to figure out how much flour is needed for 18 batches. If you need 6 cups of flour for 1 batch, then for 18 batches you will need 18 × 6, or 108 cups.
