Wei Lin is 45 years old and is considering retiring at the age of 65. Wei has $35,000 in an interest-bearing account that pays 4% compounded quarterly. Wei intends to go for a tour of the Balkan countries on the same year of the retirement (65 years of age) and has figured out that it would cost around $45,000. Wei also believes that he will survive until his age of 80. His HR department tells him that his total pension payments will be around $55,000 per year, however, in order to keep up his lifestyle, he needs to have at least $75,000/year after retirement.
