First subtract 15 from 29.
29 - 15 = 14
Now divide 14 by 7, the amount of dollars per hour.
14 ÷ 7 = 2
Mofer rented the bike for 2 hours, resulting in him paying $15 for the rent, and an additional $14 for the two hours, totalling in $29.
We can write an equation to resemble the question (h = the number of hours Mofer rents the bike).
15 + 7h = 29
~Subtract 15 to both sides
15 - 15 + 7h = 29 - 15
~Simplify
7h = 14
~Divide 7 to both sides
7h/7 = 14/7
h = 2
Therefore, Mofer rented the bike for 2 hours.
Best of Luck!
