With only a part-time job and the need for a professional wardrobe, Rachel quickly maxed out her credit card the summer after graduation. With her first full-time paycheck in August, she vowed to pay $240 each month toward paying down her $8 comma 000 outstanding balance and not to use the card. The card has an annual interest rate of 18 percent. How long will it take Rachel to pay for her wardrobe? Should she shop for a new card? Why or why not?

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.
