Question

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?

Answer 1

D= cost of discount card
  29.50 = d + 1.50(15)
  29.50 = d + 22.50
-22.50          -22.50
$7.00 = d
d = $7

Paul spent $7 dollars on the discount card.

Hope this helped :D.
