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?

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.

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
