A car rental company charges a $25.00 base fee plus $0.10 per mile driven to rent a car. How many miles did a customer drive if the customers bill was $37.80? Write the variable represents, equation, and miles.

128 miles

Step-by-step explanation:

Given that a car rental company charges a $25.00 base fee plus $0.10 per mile driven to rent a car.

Let us represent y as total charges and x no of miles driven

Even if x=0, y = 25 (base fee)

SO y intercept = 25

Slope = charge per drive = 0.10

So equation is

y = 0.1x + 25

To find out how many miles did a customer drive if the customers bill was $37.80, we can use the above equation.

y = 37.80 and x = ?

37.80=0.1x+25

0.1x = 12.80

x = 12.80/0.1 = 128 miles
