Case Study

Here is a case study about a shopper who is trying to decide if she should use a coupon.

Diane needs a couple things from the grocery store. She was in the area where she likes to shop, so she decided to stop by to pick up the things she needs. She has a coupon for $0.50 off sliced packaged turkey. Her family really likes turkey sandwiches and Diane likes serving this healthy food. Diane finds that the turkey is on sale for $1.50, and with the coupon it's only $1.00. The regular price is $2.75.

How good of a deal is the turkey using the coupon?
