Answer:
21 minutes of commercials
Step-by-step explanation:
If Hits 96 must play 3 minutes of commercials for every 30 minutes of music played, than the ratio of minutes of commercials to minutes of music is 3:30=1:10.
If 210 minutes of music is played, we can model the situation with the equation ![\frac{1}{10} =\frac{x}{210}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B10%7D%20%3D%5Cfrac%7Bx%7D%7B210%7D)
We can use cross multiply to simplify the equation to ![10x=210](https://tex.z-dn.net/?f=10x%3D210)
Dividing each side by 10, we get
So, if 210 minutes of music is played, 21 minutes of commercials is played.
