Bill Norman & Sons Medieval Funtimes sells two similar items: the Mini Trebuchet and the Tiny Ballista. If x is the selling price of one Trebuchet and y the price of on Ballista (in dollars), then Bill & Sons expect to have an annual profit (also in dollars) of P(x, y) = -3x² + 2x · y – 2y² + 350x + 375y – 3550. Make sure you answer each part. a) How much profit should they expect if each item is sold at a price of $97.50? b) Find (P (x, y)) and write its equation down. c) Evaluate (P (x, y))when z = y = 97.50. What does it mean?

A firm produces two kinds of tennis balls, one for recreational players which sells for $2.50 per can, and one for serious players which sells for $4.00 per can. The total revenue from the sale of x thousand cans of the first ball and y thousand cans of the second ball is given by R(x,y) = 2.5x+4y. The company determines that the total cost, in thousands of dollars, of producing x thousand cans of the first ball and y thousand cans of the second ball is given by C(x,y)=x^2-2xy+2y^2. Find the number of each type of ball which must be produced and sold in order to maximize the profit. a. 5000 of the $2.50 cans and 3000 of the $4 cans b. 4000 of the $2.50 cans and 3000 of the $4 cans c. 2000 of the $2.50 cans and 5000 of the $4 cans d.3000 of the $2.50 cans and 4000 of the $4 cans
