Question

Antonio is buying a stereo, speakers, and amplifiers for his car audio system. He is choosing among 4 models of stereos and 3 styles of speakers. If he has 36 different choices, how many kinds of amplifiers must there be?

Answer 1

Explanation:

First, you would multiply the 3 and 4 by eachother to get 12. When answering how many speakers there should be, I like to take the total number of choices (in this case its 36), and then divide it by the number of choices there is at the moment (12). This would get you 3 as the answer.

Answer 2

The answer is 3 or B
