# REVENUE FUNCTIONS FOR A BOOK PUBLISHER Weston Publishing publishes a deluxe edition and a standard edition of its Spanish-English dictionary. 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 are p = 20 − 0.005 x − 0.001 y q = 15 − 0.001 x − 0.003 y dollars, respectively. a. Find the daily total revenue function R (x, y). b. Find the domain of the function R

a.

To determine

To find: The daily total revenue function.

Explanation

Given:

The demand equations are,

p=200.005x0.001yq=150.001x0.003y

Where x and y are number of editions demanded per day.

Formula used:

The formula for total revenue function is R(x,y)=px+qy .

Calculation:

Substitute p=200.005x0.001y and q=150.001x0.003y in the formula given.

R(x,y)=(200.005x0

b.

To determine
