mike took a taxi to the airport and paid $ 2.50 to start plus $ 0.25 per mile. annie took a different route to the airport and paid $ 2.50 plus $ 5.00 in bridge toll fees plus $ 0.25 per mile. if each was charged exactly the same amount, and annie ' s ride was 18 miles, how many miles was mike ' s ride?
divide(subtract(add(add(2.50, 5.00), multiply(0.25, 18)), 2.50), 0.25)
"the cost of annie ' s ride was 2.5 + 5 + ( 0.25 * 18 ) = $ 12 let x be the distance of mike ' s ride . the cost of mike ' s ride is 2.5 + ( 0.25 * x ) = 12 0.25 * x = 9.5 x = 38 miles the answer is c ."
