Question

Traci wants to buy rings that cost 50$ each. A jewler is offering a deal in which you buy 1 ring and get the 2nd for 25% off and the 3rd fo 50% off. The sales tax is 8%. Traci will buy 3 rings. How much money will Traci save using the deal instead of paying full price for all rings?

Answer 1

$40.50¢

Explanation:

First Deal

Step 1: Multiply 3 rings to 50

`50 * 3 = 150`

Step 2: Find the sales tax of the total cost (result)

• Let "y" be the variable

`(8)/(100) * (150)/(y) = 12`

• Add the result to the total price

`150 + 12 = 162`

Second Deal

1 Ring = $50

2 rings = $37.5

Step 1: Find 25% off the original price

• Let "y" be the variable

`(25)/(100) * (50)/(y) = 12.5`

• Subtract the result from the original price

`50 - 12.5 = 37.5`

3 Rings = $25

Step 1: Find 50% off the original price

• Let "y" be the variable

`(50)/(100) * (50)/(y) = 25`

• Subtract the result from the original price

`50 - 35 = 25`

Total calculation

Step 1: Add all the results together

`50 + 37.5 + 25 = 112.5`

Sales Tax

Find the sale tax of the total amount of the second deal

Step 1: Let "y" be the variable

`(8)/(100) * (112.5)/(y) = 9`

Step 2: Add the result to the total price

`113.5 + 9 = 121.5`

How much was saved

Step 1: Subtract the Second deal from the First Deal

`162.0 - 121.5 = 40.5`

Taci will save $40.50 if she used the second deal instead of the first deal.

Answer 2

The first ring is $50, the second ring is 37.50 and the third ring is 25.00
The total of the rings before tax is 112.50 and $121.50 after tax
