Weston's management estimates that the number of deluxe editions demanded is x copies/day and the number of standard editions demanded is y copies/day when the unit prices in dollars, p and q, respectively, are described in the following equations.
p = 20 - 0.005x - 0.001y
q = 20 - 0.001x - 0.003y
Compute the values below of the total revenue function R with the given unit prices.
R(200 , 200) = $
R(100 , 300) = $
