If the sale price of an item is $60 after a 30% discount, what was its original price?
Options:
A) $75
B) $80
C) $90
D) $100
Answer:
C) $90
Solution:
Divide the sale price by the discount percentage and add the result to the sale price: Original price = Sale price / (1 – Discount%) + Sale price. Original price = $60 / (1 – 0.30) + $60 = $60 / 0.70 + $60 = $85.71, which rounds up to $90.
