Answer 1

$ 25.47

Explanation:

Cheese $ 2.99 / lb

Sliced ​​Ham $ 4.29 / lb

Bread $ 2.49 / loaf

Potato Chips $ 1.99 / ea OR 2 for $ 3.00

Sauce $ 3.39 / container

The coupon offer allows greater savings is the $ 4.00 coupon.

To find out which coupon means greater savings, you must do the following procedure.

1. Calculate how much is the total value of the account

Cheese - $ 2.99 / 2 = $ 1,495

Sliced ​​ham - $ 4.29 × 3 = $ 12.87

Bread - $ 2.49 × 2 = $ 4.98

Potato Chips - $ 2 for $ 3.00, so 4 for $ 6.00

Sauce - $ 3.39

$ 3.39 + $ 6.00 + $ 4.98 + $ 12.87 + $ 1,495 = $ 28.73

2. We must calculate the discount that represents 10% of the value and the 3% increase in food tax.

$ 28.73 / 100 = $ 0.287

0.287 × 10 = $ 2.87

$ 28.73 - $ 2.87 = $ 25.87

$ 28.73 / 100 = $ 0.287

0.287 × 3 = $ 0.861

$ 25.87 + $ 0.861 = $ 26.73

3. We must calculate the discount represented by the $ 4 coupon and the 3% food tax increase.

$ 28.73 - $ 4.00 = $ 24.73

24.73 / 100 = $ 0.24

0.24 × 3 = $ 0.74

$ 24.73 + $ 0.74 = $ 25.47
