Consider an individual who currently earns $20,000 as an unskilled laborer. Suppose that by taking courses full-time at a community college for one year, the person can qualify for a more skilled job paying $23,000 that is guaranteed to last for 10 years (after which the person would retire). Assume the cost of tuition and books at the community college for one year is $2,000 and that the current interest rate is 6%. Is this a good investment
