Make an equation
Y = 17.95 + 0.87x
Y = total cost, x = miles
153.67 = 17.95 + 0.87x
135.72 = 0.87x
x = 156 miles
Y = 17.95 + 0.87x
Y = total cost, x = miles
153.67 = 17.95 + 0.87x
135.72 = 0.87x
x = 156 miles
Answer:
Jim drove the truck 156 miles
Step-by-step explanation:
Represent the number of miles driven with x.
Then the formula for the total rental cost is C(x) = $17.95 + ($0.87/mile)x, and this comes to $153.67. Solve for x:
$153.67 - $17.95 = ($0.87/mile)x, or
$135.72 = ($0.87/mile)x
Dividing both sides by ($0.87/mile), we get:
x = 156
