Last year, Jarod left a job that pays $80,000 to run his own bike-repair shop. Jarod’s shop charges $65 for a repair, and last year the shop performed 5,000 repairs. Jarod’s production costs for the year included rent, wages, and equipment. Jarod spent $60,000 on rent and $100,000 on wages for his employees. Jarod keeps whatever profit the shop earns, but does not pay himself an official wage. Jarod borrowed $30,000 for the shop’s equipment at an annual interest rate of 4 percent.
