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?
