Question

Paul bought a student discount card for the bus. The card allows him to buy daily bus passes for $1.70. After one month, Paul bought 22 passes and spent a total of $45.40.

How much did he spend on the student discount card?

Paul spent $___ on the student discount card.

Answer 1

Explanation:

C= total cost

D+ discont card

n = daily passes

C=d+1.70n

C is revealed to be 45.40 and n is 22

45.40= d + 1.70(22)

45.40= d + 37.40

45.40-37.40 = 8 + d

the discount pass was $8
