Question

Oceanside Bike Rental Shop charges $16 plus $6 an hour for renting a bike. Melanie paid $64 to rent a bike. How many hours did she pay to have the bike checked out?

Answer 1

Melanie payed for 8 hours to have the bike checked out.

Explanation:

You just have to do the opposite steps shown in the problem, but you have to subtract the $16 fee from $64 first.

$64-$16= $48

$48 divided by $6 = 8 hours

I hope this helps!

Answer 2

This is a linear equation.

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
