Leroy purchased an AI-based robotics system with the first cost of $345,000, an AOC of $148,000 per year, a $140,000 salvage value, and an ESL of 3 years. Rather than trading after 3 years, he kept the system for a total of 5 years. Due to the wear factor and expense of repairs, its AOC increased to $220,000 per year starting in year 4, plus the salvage value went to zero. At i = 10% per year, what is the percentage increase in the AW of costs that Leroy experienced? The percentage increase in the AW of costs that Leroy experienced is __ %

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.
