Paul bought a student discount card for the bus. the card allows him to buy daily bus passes for $1.50. after one month, paul bought 15 passes and spent a total of $29.50. how much did he spend on the student discount card?

I think it would be $22.50 assuming you multiply 15 and $1.50 to get your answer.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
