Answer 1

Answer:

She will pay $13.20 altogether.

Step-by-step explanation:

1. 40% of 20 is 8.

Write 40% as 40/100.

40/100 of 20 = 40/100 × 20.

2. Sale Price = $12. This means the cost of the dress to Molly is $12. She will pay $12 for a dress with an original price of $20 when discounted 40%.

3. The 10% tax will be $1.20. When a store-issued coupon is redeemed, the sales tax is based on the discounted price (the cost of the item after the coupon is applied). So multiply 12 x 0.10 and you will get 1.20.

4. After tax is added to the sale price, she will pay $13.20.

12.00 + 1.20 = 13.20.
