Bell Motors manufactures two models of electric cars. The demand equations giving the relationship
between the unit price, p and q, and the number of cars demanded per year, x and y, of Models S1 and S2
are
p=60,000-4x-2y and q=50,000-2x-4y
respectively. Note: x and p go with Model S1 and y and q go with Model S2, and in general,
Revenue = [number of units produced] x [price demanded at the units produced].
a. Create the total yearly revenue function R(x, y).
b. What is the total revenue realized by Bell motors if it sells 3000 Model S1s and 2000 Model S2s.
