Answer:
- The original price of the bicycle is $112.38
--------------------------
Let the original price of the bicycle be x.
Set up an equation to reflect the discount:
Solve the given equation for x:
- x - 0.2x = 89.90
- 0.8x = 89.90
- x = 89.90/0.8
- x = 112.38 (rounded to full cent)
Hence the original price is $112.38.
