oceanside bike rental charges fourteen dollars plus nine dollars an hour for renting a bike. Dan paid fifty nine dollars to rent a bike. How many hours did he pay to have the bike checked out?

7 hours

Step-by-step explanation:

y = mx+b

y is the total cost.

The slope m is the rate: that's 9 dollars per hour.

x is the number of hours.

b is the initial value: 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
