To explain: If the thought of finishing an expensive meal even if the appetite is full is right or not.
Concept Introduction:
Sunk costs are costs which cannot be recovered once it’s incurred. The business does not consider sunk costs when planning on the production or selling of the goods, because they cannot alter these costs to reduce total costs or increase revenue. Sunk costs are a part of every business organization. Thus, one can work effectively to reduce these sunk costs.

Explanation of Solution
Since the cost of the expensive meal is already incurred, it cannot be recovered. Thus, it is a sunk cost. Since now the sunk cost is already incurred, it should not be considered in the decision making to maximize utility. Thus, if an individual cleans their plate despite being full, they are reducing their utility because they have already received the maximum utility from the dish when they are full. Irrespective of eating the entire dish or leaving it halfway, still means you have paid for the entire dish. Thus, one can rather choose to share the dish or pack the leftovers to eat at home, thus, keeping their utility intact.

- A village has six residents, each of whom has accumulated savings of $100. Each villager can use this money either to buy a government bond that pays 18 percent interest per year or to buy a year-old llama, send it onto the commons to graze, and sell it after 1 year. The price the villager gets for the 2-year-old llama depends on the quality of the fleece It grows while grazing on the commons. That in turn depends on the animal's access to grazing, which depends on the number of llamas sent to the commons, as shown in the following table: Number of 11amas on the commons Price per 2- year-old 11ama ($) 1 125 2 119 3 116 4 113 5 6 111 109 The villagers make their investment decisions one after another, and their decisions are public. a.
