MegaMart collects a sales tax equal to 1/16 of the retail price of each purchase and sends this money tp the state government.

a. Is the amount of tax collected proportional to the cost of an item before tax is added?

b. Is the amount of tax collected proportional to the cost of an item after tax has been added?

    yes, yes

    Tax=1/16* price
    cost=tax+price=1/16 price+price=17/16* price
