Question

An aquarium is on sale for $59.50. This is a 15% discount from the original price. What was the original price?

a) $64
b) $65.75
c) $50.25
d) $70

Answer 1

The original price of the aquarium before a 15% discount was applied is $70. To find this, divide the sale price of $59.50 by 0.85 (which represents the remaining 85% of the price after the discount).

Step-by-step explanation:

To find the original price of the aquarium before the 15% discount, we can use the formula: Original Price = Sale Price / (1 - Discount Rate). The sale price is given as $59.50 and the discount rate is 15%, or 0.15 in decimal form. Using the formula, the original price is calculated as follows:

Original Price = $59.50 / (1 - 0.15) = $59.50 / 0.85 = $70

Therefore, the correct answer is d) $70. This is the price before a 15% discount was applied to give the sale price of $59.50.
