Justin bought a calculator and a binder that were both 15% off the original price. The original price of the binder was $6.20. Justin spent a total of $107.27. What was the original price of the calculator?

9514 1404 393

  $120

Step-by-step explanation:

Let c represent the original price of the calculator. Then the amount Justin spent was ...

  (6.20 +c)(1 -0.15) = 107.27

  6.20 +c = 107.27/0.85 . . . . . divide by the multiplier on the left

  c = 126.20 -6.20 . . . . . . . . . . subtract 6.20

  c = 120

The original price of the calculator was $120.
