A car rental cost ​$90 per​ day, for the first 230 ​miles, plus ​$0.20 for each additional mile. If​ Sonya's rental cost was ​$134 for a​ one-day rental, how many miles did she​ drive?

Answer 1

Hi Destiny, let x represent the number of miles driven over 230. The equation for total cost is:

90 + .2 * x = 134

Solve for x, subtract 90 from both sides:

.2 * x = 134

Divide both sides by .2:

x = 220

Sonya drove 220 miles over the allotted 230

Sonya drove a total of 450 miles.
