Redo Problem 12 given the following inverse demand functions:
Px = 1000 - 20x - 3y and Py = 500 - 5y - 2x
In Problem 12
a. What bundle of products (x*, y*) should the firm produce?
b. What prices will the firm be able to charge for each product given production at (x*, y*)?
c. What profits result in this instance?
d. At (x*, y*), what are the values of

Provide a short (one- or two-sentence) explanation for each value. That is, explain to your less mathematically sophisticated boss the economic significance of each value.
e. check your work by determining the profits that result if x and y are one unit more or less than optimal and fill in the following table
