Question

justin timberlake needs new microphones and speakers for his next concert.for a total of 291, he can buy 6 speakers and 3 microphones if he buys 9 speakers and 11 microphoes then the total is 586 find the cost of one microphones

Answer 1

Based on my calculations, I think that 8 is the answer.

Explanation:

An easy explanation would be:

291 / 6 = 48.5 Well, we need to find out how much 1 microphone costs, so then you divide 48.5 by 3 which gets you 16.167 or 16.16666 repeating.

You need to divide that by two which gets you 8.0835, or rounded down, 8.
