Answer:
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

Answer:
Melanie payed for 8 hours to have the bike checked out.
Step-by-step 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!
