Traveling carnivals move from town to town, staying for a limited number of days before moving to the next stop. The management of a certain carnival knows that each
time it opens in a new town, it can expect to bring in about $15,000 in revenue the first night. Each night after the first revenue will be about 75% of the previous night's
revenue.
To the nearest dollar, about how much revenue can the carnival anticipate on its 5th night in town?
