Let y = total charge for a car rental and x = miles driven
Proxy car equation: y = 0.32x + 18
YourPal equation: y = 0.36x + 12
Set equations right sides equal to each other... meaning their cost, y, are equal
0.32x + 18 = 0.36x + 12
18 = 0.04x + 12 (subtract 0.32x from both sides of the equation)
6 = 0.04x (subtract 12 from both sides of the equation)
150 = x (divide both sides of the equation by 0.04)
ANSWER: 150 miles
(4 3/8) + (5 1/3)
(4+5)(3/8 + 1/3)
9 + (17/24)
she ran 9 17/24 miles total
To find the amount that Franklin financed, you will calculate the amount he put down and subtract that from the original price because that is what he still owes.
0.2 x $4500 = $900
$4500 - $900 = $3600.
Porter financed $3600.
You also multiply 0.8 x $4500 because this represents the part out of 100% he still owes. You will get the same answer this way.
