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

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

Answer 2

Answer:

$40.50¢

Step-by-step explanation:

First Deal

Step 1: Multiply 3 rings to 50

$50 \times 3 = 150$

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

• Let "y" be the variable

$\frac{8}{100} \times \frac{150}{y} = 12$

• 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

$\frac{25}{100} \times \frac{50}{y} = 12.5$

• 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

$\frac{50}{100} \times \frac{50}{y} = 25$

• 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

$\frac{8}{100} \times \frac{112.5}{y} = 9$

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.
