First looking at this, you know that she can't rent the car for more than 1 week, since she will spend more for the second week, which will take away from the amount of miles she can drive (in this case, renting for 2 weeks would also put her over her budget).  

Therefore (if x is the amount of miles she drives):$$AMOUNTPAID = $80 + .18x$$ If AMOUNTPAID = $150 (her budget):$$$150 = $80 + .18x$$ $$x = 388.888889 miles = 388 miles$$

subtract 80 from 150 the cost for the car, then divide the answer by 18 cents( the charge per mile) good luck
