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) = 6x + By C(x,y) = x2 4xy + 9y2 + 28x -126y 2 Determine how many of each type of solar panel should be produced per year to maximize prot. The company will achieve a maximum prot by selling solar panels of type A and selling solar panels of type B
