Question

From the grocery store you need to purchase 1/2 lb cheese, 3 lbs sliced ham, 2 loaves of bread, 4 bags of potato chips, and 1 container of salsa. You have a coupon for $4.00 off if your purchase totals more than $15.00 or 10% off if the total is more than $20.00. The food sales tax is 3%. Which coupon offer will save you the most money?Item Cost
Cheese $1.99/lb
Sliced Ham $3.29/lb
Bread $1.59/loaf
Potato Chips $1.99/ea OR 2 for $3.00
Salsa $1.39/container

Answer 1

so
multiply the quantity of each item by the price per unit
then add up the cost

now, with that total, calculate
1. the price with the 4 dollars off 15 coupon applied
and
2. the price with the 10% off 20 dollars coupon applied

apply the sales tax to both 1 and 2. see which total is smallest at the end.
