During a sale arianna purchases a sweater listed at $100 . With 20% off and 7% sales tax, How much did she pay for hte discounted sweater

100 * 0.80 * 1.07 = ?

To calculate how much Arianna paid for the discounted sweater, we'll need to calculate the amount she saved with the 20% discount and then add the 7% sales tax.

1. Calculate the amount saved with the 20% discount:
- Multiply the original price of the sweater by the discount rate: $100 * 0.20 = $20

2. Calculate the discounted price:
- Subtract the amount saved from the original price: $100 - $20 = $80

3. Calculate the amount of sales tax:
- Multiply the discounted price by the sales tax rate: $80 * 0.07 = $5.60

4. Calculate the final amount Arianna paid:
- Add the discounted price and the sales tax: $80 + $5.60 = $85.60

Therefore, Arianna paid $85.60 for the discounted sweater after applying the 20% off discount and adding the 7% sales tax.
