The company is considering two alternatives to maximize its profit. The first alternative is to continue manufacturing canisters and selling them as before. The second alternative is to buy the canisters from outside and focus on manufacturing cups instead. The calculations show that buying the canisters and focusing on cups would lead to a higher total profit of $700,000 compared to the current approach. However, other factors such as quality control, timely delivery, and after-sales service should also be considered when making this decision.
