My sister is debating pursuing an LPN degree which requires 2 years of college (Ivy Tech costs $6000/year) and typically pays $28000/year or an RN Associates degree which requires 3 years of college and typically pays $35000/year. She would have to give up her full-time job as a CNA which pays $17000/year in order to go to school. Assume a prevailing interest rate of 7%. Which program should she pursue? Begin by considering only private costs/benefits and calculate NPV. Show your work! Then discuss other factors she should consider.
