Question

Four sisters contributed equally to buy a present for their father. They received a 10% discount on the original price of the gift. After the discount was taken, each sister paid $13.50. What was the original price of the gift?

Answer 1

Answer:

54 dollars

Step-by-step explanation:

This is the price AFTER the discount

Let x be the price before the discount

-------------------------------------------------------

Price after discount = (price before discount) - (10% of price before discount)

54 = (x) - (10% of x)

54 = x - 0.10x

54 = 0.90x

0.90x = 54

0.90x/0.90 = 54/0.90 Divide both sides by 0.90 to isolate x.

x = 60

So the price before the discount was $60.
