Question1

Find Cy(x,y) if C(x,y) =6x +9xy -7y +4x -7y -8 Cxy ( X, y ) =A company produces two types of solar panels per year: x thousand of type A and y thousand of type B. The revenue and cost equations, in millions of dollars, for the year are given as follows. R(X,y) = 3x + 4y C(x,y)= x2 -3xy +6y2+6x-38y -9 Determine how many of each type of solar panel should be produced per year to maximize profit. The company will achieve a maximum profit by selling solar panels of type A and selling solar panels of type B The maximum profit is $ million
