plan A: $30 per day and $.13 per mile Plan B: $50 per day with free unlimited mileage for what range of miles will Plan B save you money for a one day rental

Question

give answer accurate to at least one decimal place

Answer 1

0.13x + 30 = 50

0.13x = 20

x = 153.8

The costs are the same if 153.8 miles are driven.

If you drive more than 153.8 miles, then Plan B is cheaper.
