You started working today, and you opened a $401$k account with your employer. Your employer will match all contributions to your $401$k account on a one$-$to$-$one basis. You estimate that you can earn an average annual return of $8\%.$ If you want to have $$3,000,000$ in $40$ years, and you start contributing to your $401$k a month from today, how much do you have to contribute to the account each month?
