93.75

Step-by-step explanation:

well think about this he purchased 7 songs then he is left with $ 41.25 on his card then he bought 18 songs for 27.50 would tell you how much was used what it wants is for you to figure out the starting number using the equation 7+18 = 25 and 41.25+27.50 = 68.70. which would make 68.70 + 25 = 93.75
