Answer:
4 hours
Explanation:
Decorations and refreshments already cost $172, so subtract 172 from 380
380 = 172 = 208
The band charges a $100 flat fee, so subtract 100 from 208
202 - 100 = 108
We have $102 remaining
To find how many hours the band can play, divide 108 by 25
102 ÷ 25 = 4.32
You can't buy 0.32 hours, so round that 4.32 down to 4
