Mike would like to buy a shirt at a store which has special sale for the weekend. He wants to
find the total cost, with tax, before going to the counter. The price of the shirt is 5 dollars less
than the original price, and the tax rate is 8%. If f(x) represents the price of the shirt after the
discount is applied and g(x) represents the cost of the item with tax, write a composition of
functions to represent this scenario.
