Your employer automatically puts 5 percent of your salary into a 401(k) retirement account each year. The account earns 10% interest. Suppose you just got the job, your starting salary is $60000, and you expect to receive a 2.5% raise each year. For simplicity, assume that interest earned and your raises are given as nominal rates and compound continuously. Find the value of your retirement account after 20 years
