The plaid flannel shirt that you have

wanted for months is now on sale at the mall for $35. Sales tax at the

mall is 7%. Before you leave to buy the shirt, you see an ad for the

same shirt for $30 with a sales tax of 9.5% at a shop 20 miles away.

Decide which shirt is the better buy and tell why. Can you think of one

reason that would make the more expensive shirt a better buy?
