1 Optimizing Production Efficiency: A Study on Production Possibility Frontier

Timmy and Tommy both work at Nook's Cranny, a general store, where they spend all of their time doing one of two tasks: developing crafting projects and placing orders. The graph below shows their production possibilities frontiers for a day of work. Assume they operate efficiently all the time. Use this information for the following 2 problems.
