Step 2: Find the sales tax of the total cost (result)
@@MATH_TOKEN_1@@
- Add the result to the total price

Second Deal
1 Ring = $50
2 rings = $37.5
Step 1: Find 25% off the original price
@@MATH_TOKEN_3@@
- Subtract the result from the original price
@@MATH_TOKEN_4@@
3 Rings = $25
Step 1: Find 50% off the original price
\(\frac{50}{100} \times \frac{50}{y} = 25\)
- 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.
