Question

12. A DJ for the school dance plans to play

dance music for two hours. She has 20
requests for songs, and each song plays 31/2 minutes. If she playa all of the requests, how much time will she have to play other songs?

Answer 1

50

Explanation:

So, put 2 hours into minutes. You get 120. Now, seeing how you have 20 song requests, and each one takes 3.5 minutes, multiply those two values. Now you have 70. After doing that, just subtract 70 from 120 and get 50.
