Products A and B are produced using a production line that has two machines denoted as X and Y. Product A takes 5 minutes per unit in Machine X and 15 minutes per unit in Machine Y. Product B takes 10 minutes per unit in Machine X and 5 minutes per unit in Machine Y. Selling price per unit are $30 for Product A and $40 for product B. Variable costs per unit are $10 for Product A and $28 for Product B. Suppose that Management has decided to produce at least 2 units of A. The rest of the capacity may be used for A and B in any combination to maximize gross profit per hour. The best combination of production of A and B (assuming only integer number of units per hour of each product may be produced) and the corresponding gross profit per hour will be

X: 5 mins for A and 10 for B Y 15 mins for A and 5 for B A or B Produce three units of A and 3 units of B for a gross profit per hour of $210. Produce two units of A and 5 units of B for a gross profit per hour of $100. None of the above. Produce two units of A and 5 units of B for a gross profit per hour of $260. Produce four units of A and 0 units of B for a gross profit of $120
