Joe Smith’s employer offers its employees a two month unpaid vacation after 7 years of employment. Joe would like to go to New Zealand for his time off but has just started working for the firm. He estimates that his trip will cost $20,000. He plans to make an annual deposit of $2,500 (1 year from today) and the account will pay him a rate of 9% annually. Will this deposit be enough to pay for his trip? If not, how much would he need to deposit each year in order to have enough money?
