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 + 5y C(x.y) = x2 - 3xy + 6y2+4x -34y -6 Determine how many of each type of solar panel should be produced per year to maximize profit
