Final answer:
The decision of whether to proceed with the fireworks display should consider the costs and benefits for each town. Each town should calculate the total costs and benefits based on the enjoyment levels of its members. It is also important to consider the opinions and preferences of all the townspeople.
Step-by-step explanation:
To determine whether the towns should go ahead with the fireworks display, we need to consider the costs and benefits for each town. Let's calculate the total costs and benefits for one town as an example.
Each town has three members, so the total cost for the fireworks display is $300. Suppose some people in the town enjoy fireworks more than others. If the fireworks display is held, the benefit for each person who enjoys fireworks could be $100, while the others might not receive any benefit. Therefore, the total benefit for the three members who enjoy fireworks is $300, which is the same as the cost. In this case, it would be reasonable for the town to go ahead with the fireworks display.
However, it is important to note that this calculation does not take into account any personal preferences or factors such as financial constraints. The decision of whether to proceed with the fireworks display should also consider the opinions and preferences of all the townspeople.
