Question

Tony rents a bike that costs $4 per hour and $10 for the lock. He has $32 to spend. How long can he rent the bike? Write an equation that represents this situation. Be sure to explain how you got your equation and specify what the variables represent.

Answer 1

he can rent the bike for 5 hours

Explanation:

32-10=22

22*4=5

Answer 2

5 hours; 4x+10=32

Explanation:

4x = 4 multiplied by the amount of hours

10 = the cost for the lock

so y = 4x+10

In this case y= 32 so plug it in

4x+10=32

-10 -10

4x=22

/4 /4

x=5.5

So assuming you can only rent whole hours, it would be 5 hours

Hope this helps.
