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) = 5x + 6y C(x,y)=x2-3xy + 8y2 + 15x - 78y - 6 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
