b. Suppose instead that the demand curve is actually nonlinear and all costs disappear (covered by a mysterious and generous benefactor). Specifically, P[Q] =75 – Q², which implies that total revenue is TR[Q] = Q*P[Q] = Q(75 – Q²) = 75Q – Q³, and then marginal revenue is MR[Q] = dTR/dQ = 75 – 3Q². Compute your profit-maximizing price (P*), quantity (Q*) and Profit (*). TIPS: If all costs are zero, then how is profit related to revenue? How could you find the highest point of a hill- shaped curve? For a picture of TR, try Googling graph 75x-x^3

This ended up being wrong. Can you please re-do? Thanks

Imagine you are the mayor of a town and you are trying to decide if you should pay for a fireworks show. Your staff survey your 400 citizens who say that they each value a fireworks show at $10. The fireworks show only costs $3,000 so you put on the show but when you ask for donations to pay for the fireworks you only receive $25 total. What does this result show? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. You staff's survey must have overestimated the value of a fireworks show. b The fireworks cost must have been greater than their economic benefit. The firework show suffered from the Tragedy of the Commons problems d The town's citizens were free-riders.
