Provide an appropriate response.To make some extra money, you make two types of picture frames, type A and type B, for sale. You have an initial start-up expense of $75. The production cost for type A is $3.60 per frame, and the production cost for type B is $5.20 per frame. The price for type A is $6.00 per frame and the price for type B is $10.00 per frame. Let x be the number of type A and y be the number of type B produced and sold. Write an inequality describing revenue less than cost. Solve the inequality and describe the region. Also, describe what this means in terms of frames.
