Alexandra needs to rent a car while on vacation. The rental company charges $18.95, plus 17 cents for each mile driven. If Alexandra only has $40 to spend on the car rental, what is the maximum number of miles she can drive?
M = miles driven....and we have
18.95 + .17M = 40 subtract 8.95 from both sides
.17M = 21.05 divide both sides by .17
M = 21.05 / .17 =21.05/.17 = 123.82 ≈ 123 miles
