Question

12-packs Of Skwunch apple juice cost $3.00 after a 40% discount. Which equation would allow you to find the original price of the 12-pack? PLEASE HELP!!!!!!

Answer 1

100/40 = 2.5

Mulitply 2.5 by 3

2.5 * 3 = 7.5

The original price is $7.50

Answer 2

3.00 = original price * (1-.4)

or

3 = original price*.6

Explanation:

We know the cost after the discount.

Price after discount = original price - original price * discount rate

Factoring out the original price

Price after discount = original price (1- discount rate)

We know the price after discount = 3.00 and the discount rate =.40

Substituting these values in

3.00 = original price * (1-.4)

3 = original price*.6

Divide each side by .6

3/.6 = original price

5.00 = original price
