Question

Mrs. Scott rented a jeep. The rental charge is a flat fee of

$115 plus $12.50 per hour. Her bill is $152.50, not
including tax. Write and solve an equation that could be
used to find the number of hours she rented the jeep

Answer 1

Answer is $152.50 = $12.50x + $115

Step by step

Using y intercept form
y = mx + b

Flat fee of $115 is y intercept or “b”
The $12.50 per hour is the rate or “m”
$152.50 is the total

So your equation is

$152.50 = $12.50x + $115

To solve subtract $115 from both sides to isolate x

$152.50 - $115 = $12.50x + $115 -$115

$152.50 = $12.50x

Divide both sides by $12.50 to solve for x

x = 12.2 hours
