Answer:
1. The 401k plan allows him to use pre-tax dollars to invest for his retirement.
Step-by-step explanation:
A 401k plan allows an individual to save money for retirement without paying income taxes for each contribution that he/she makes to the retirement plan. The individual will pay income taxes only after he/she retires and starts withdrawing out of the 401k plan (it is a tax deferred account). Employer's matching of 401k contributions are also taxed once you start withdrawing money. The tax free contributions allow the 401k account to grow faster and earn more money.
