A. Rough Stuff makes 2 products: khaki shorts and khaki pants for men. Each product passes through the cutting machine area, which is the chief constraint during production. Khaki shorts take 15 minutes on the cutting machine and have a contribution margin per pair of shorts of $15. Khaki pants take 24 minutes on the cutting machine and have a contribution margin per pair of pants of $30. If it is assumed that Rough Stuff has 4,800 hours available on the cutting machine to service a minimum demand for each product of 3,000 units, how much will profits increase if 112 more hours of machine time can be obtained?

C. Syntech makes digital cameras for drones. Their basic digital camera uses $80 in variable costs and requires $1,600 per month in fixed costs. Syntech sells 100 cameras per month. If they process the camera further to enhance its functionality, it will require an additional $50 per unit of variable costs, plus an increase in fixed costs of $1,000 per month. The current price of the camera is $150. The marketing manager is positive that they can sell more and charge a higher price for the improved version. At what price level would the upgraded camera begin to improve operational earnings?
