A small company that builds wooden fences can currently construct five fences per month for a total revenue of $5,000 and a total cost of $750. One month, the firm owner decides to invest in more equipment. This extra equipment allows the company to build a sixth fence per month, but raises total cost to $825. Assuming the firm charges the same price for the sixth fence as it did for each of the other five, what is the change in total profit that results from increasing output?

The business cycle is the periodic but irregular up-and-down movement in economic activity, measured by fluctuations in real gross domestic product (gdp) and other macroeconomic variables. a business cycle is typically characterized by four phases—recession, recovery, growth, and decline—that repeat themselves over time. economists note, however, that complete business cycles vary in length. the duration of business cycles can be anywhere from about two to twelve years, with most cycles averaging six years in length. some business analysts use the business cycle model and terminology to study and explain fluctuations in business inventory and other individual elements of corporate operations. but the term "business cycle" is still primarily associated with larger (industry-wide, regional, national, or even international) business trends.
