Question

A bike store rents bikes for $9 an hour in addition to a helmet rental fee of $15. If

Emmanuel paid $51, for how many hours did he rent the bike?

Answer 1

4 hours

Explanation:

First we need to subtract the one pay fee (the helmet rental fee, $15)

So 51 - 15 = 36

Then we need to divide 36 by the amount of money it costs for each hours to find how many hours he rented the bike

So 39/9 = 4
