Question

The local bike shop rents bikes for $18 plus $6per hour. Bill paid $36 to rent a bike. For howmany hours did he rent the bike for?

Answer 1

we have:

h = hour

the equation is

$\begin{gathered} 18+6h=36 \\ 18+6h-18=36-18 \\ 6h=18 \\ \frac{6h}{6}=\frac{18}{6} \\ h=3 \end{gathered}$

answer: 3 hours
