Michael rented a truck for one day.a base fee of $18.99, an additional charge of 80 cents for each mens Michael $253.39 when truck returned

Question

I need to find out how many miles.

Answer 1

We can set up an equation to represent this situation:

 

y = 0.80x + 18.99

 

The $18.99 is a flat fee that the rental company charges, regardless of the number of miles you drive.  They charge you an additional $0.80 per mile on top of the flat fee.  We can plug in $253.39 in for y and solve for x (the number of miles driven):

 

253.39 = 0.80x + 18.99

234.4 = 0.80x

293 = x

 

Michael drove 293 miles.
