Question 394003
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.
---
Revenue = price*quantity
R(p) = p(2000-100p)
R(p) = 2000p-100p^2
================================
b) Find 
R(5) = 2000*5 - 100*5^2 = 10,000-1000 = 9000
-------- 
R(10) = 2000*10-100*10^2 = 20000-10000 = 10,000
-------- 
R(20) = 2000*20 - 100*20^2 = 40000-40000 = 0
=================
