Question

The Party Room at Penny’s Pizza rents for an initial fee of $20 and then $5 per hour. Aislyn ’s bill for her birthday party was $40. For how many hours did she rent the room?

Answer 1

4

Answer 2

20+5x=40
solve for x

Answer 3

20 divided by 5 = 4
So 4 hours
Why 20? because 20 dollars was the first fee and you have to subtract that from teh bill to figure out how much you spent for hours. Then it was 5 dollars per hour and how many hours could you get out of 20 bucks. There's where 20 divided by 5 comes from.
