Simon, 35, works for a company which offers a 4% match to his 401(k) plan. he previously invested $25,000 into an ira. what would be the most beneficial retirement investing strategy for simon?

If i had to take a guess i would say a 401k plan. Its one of the best ways to save for retirement. Why you ask? Well because you keep saving over time. As time goes on money will be added to the account. Not only are you adding money to this account the bank pays interest for you. An IRA is just an individual savings account. In an IRA you just keep stocks, bonds, mutual funds and other assets in there. Plus you are not getting paid interest for the IRA. 

401k plan, Hope i can help
