4) Oceanside Bike Rental Shop charges $17 plus $6 an hour for renting a
bike. Tim paid 59 dollars to rent a bike. For how many hours did he check
out the bike?

Respuesta :

Answer:

It is 7

Step-by-step explanation:

y = mx+b

y is the total cost.

x is the number of hours.

b : that's 16 dollars.

y = 9x+16

 

The problem states that the cost was 79 dollars.

Substitute that for y and solve for x.

79 = 9x+16

63 = 9x

x = 7 hours
