Coupon 1

Step-by-step explanation:

Purchase list :

1/2 lb cheese

3 lbs sliced ham

2 loaves of bread

4 bags of potato chips

1 container of salsa.

Cost of 1 lb cheese = $1.99

So, cost of 1/2 lb =

                            =

Cost of 1 lb sliced Ham = $3.29

So, cost of 3 lb Sliced Ham =

                                             =

Cost of 1 loaf of bread = $ 1.59

So, cost of 2 loaves of bread =

                                                =

Cost of 2 bags of potato chips = $ 3

So, cost of 4 bags = $3+$3  = $6

Cost of 1 container of salsa = $1.39

So, total cost of purchase before sales tax = =

Now The food sales tax is 3%.

So, 3% of total =

                        =

                        =

Thus total cost including sales tax =

                                                        = $22.036

Coupon 1: $4.00 off if your purchase totals more than $15.00

Since total cost is more than $15

So, $4 is off on total cost

So, total cost after coupon is applied = $22.036-$4 =$18.036

Coupon 2:  10% off if the total is more than $20.00.

So, 10% of total cost =

                                  =

                                  =

So, total cost after getting 10 % off =

                                                          =19.8324

So, total cost after coupon 2 is applied = $19.8324

Hence coupon 1 will save the most money .
