You have several purchases you need to make from the grocery store. from the grocery store you need to purchase 1/2 lb of cheese, 2lbs sliced ham, 2 laoves od bread, 3 bags of potato chips, and 2 comtainers of salsa. you have a coupon for $3.00 off if your purchase totals more than $25.00 or 10% off if the toral is more than $30. the sales tax is 4%. what is your total purchase?

The subtotal before tax and coupons is

... (2.99/lb × 1/2 lb) + (4.29/lb × 2 lb) + (2 loaves × 2.49/loaf) + (3 bags × 3.00/(2 bags)) + (2 salsa × 3.39/salsa) = 1.50 +8.58 +4.98 +4.50 +6.78

... = 26.34

This total is more than 25.00, but less than 30.00, so you get 3.00 off. The amount before tax is

... 26.34 - 3.00 = 23.34

4% tax is 0.04 × 23.34 = 0.93

so the total purchase comes to

... $23.34 + 0.93 = $24.27

this doesn't make sense lol
