A bike rental costs $8 plus $3 per hour. Ravi spent a total of $29 for a bike rental. For how many hours did he rent the bike?

7 hours

Step-by-step explanation:

basically the fine for using the bike is 8 dollahs then 3 dollahs per hour the bike is used so the equation will look like this. h equals hours

3h+8=29

solve like any other equation

subtract 8 from both sides. 3h+8-8=29-8

rewrite the equation 3h=21 now isolate the variable divide by 3 from both sides of the equation

3h/3=21/3

rewrite the equation h=7

he rode for 7 hours
