Sales tax in Pennsylvania is 6%. Create an equation for the total price (cost plus tax) of a purchase in PA in terms of its cost. How much would a person pay for a car whose cost is $32,000?
PAY = COST + 0.06 * COST
P=C(1+1.06)
P=1.06C
P= (32,000)= 1.06*32000= $33920.00
HOW WOULD I SHOW A GRAPH ON THIS PROBLEM?
You could show a pie-chart which shows how much of the price is the tax, and how much is the cost.
There could be other options.
