(14-16). A new mattress at the Mattress Store cost $625. They are running a Christmas sale where I can save off the original price. Tax in Indiana is 7% ? How much money did I save from the discount?

How much did I pay in tax?

What would be the final cost of the mattress after the discount and tax are applied?
