ABC Electronic Co. is trying to determine how many TVs and stereos to make for the coming year. The company can sell each TV for $1000 and each stereo for $500. The variable costs to produce the TV are $650, while the variable costs for the stereo are $250. The number of TVs produced cannot be greater than 1000 due to the space restriction in the warehouse; however, stereos are smaller and there is room for 5000. It takes 6 machine hours to make each TV and 4 machine hours to make each stereo. The factory has 25000 machine hours available per year. Let T = TVs and S = stereos. How many of each should ABC Electronic Co. produce in order to maximize its contribution margin
