Selling shirts. If a vendor charges p dollars each for rugby shirts, then he expects to sell 2000  100p shirts at
a tournament.
a) Find a polynomial R(p) that represents the total revenue
when the shirts are p dollars each.
I came up with the polynomial being:
R(p)= 2000100p^2
b) Find R(5), R(10), and R(20).

Your math is ok, but your given data makes little sense.
e.g. at R(5) = 2000  100(25) = 500
he would be losing 500 dollars if he charges $5 per shirt
If he gave the shirts away (no charge for a shirt or R(0)), his revenue would be 2000 ???? 
Swimming space. The length of a rectangular swimming pool is 2x 1 meters, and the width is x + 2 meters. Write a polynomial a(x) that represents the area. Find A (5).
