Mary got a 30 year Fully Amortizing FRM for $1,000,000 at an annual interest rate of 7% with monthly payments. After 5 years of payments, Mary can refinance the balance into a 25 year Fully Amortizing FRM at an annual interest rate of 6%, with monthly payments. Refinancing will cost Mary 1 point and $1,500 in closing costs. If Mary refinances into this loan and makes payments for 25 years, what will be her return on investment from refinancing

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.
