Question

a couple has decided to increase their income from investments for when they retire in twenty years. which is the best way they can accomplish that goal?
by enrolling in a 401k and investing in the stock market
by opening a savings account and investing in commodities
by buying cds and us government bonds
by opening an ira and investing in a new business

Explanation:

To determine the best way to increase investment income for retirement in 20 years, we analyze each option:

• Option 1 (enrolling in a 401k and investing in the stock market): 401k plans offer tax - advantaged growth, and over a 20 - year horizon, the stock market has historically provided relatively high returns (though with volatility, which is mitigated over long time periods).
• Option 2 (savings account and commodities): Savings accounts have low - return rates, and investing in commodities is highly volatile and not ideal for long - term retirement savings as a primary strategy.
• Option 3 (buying CDs and US government bonds): CDs and government bonds have relatively low returns compared to the stock market over a 20 - year period, and they won't grow the investment as much to meet retirement income goals.
• Option 4 (opening an IRA and investing in a new business): Investing in a new business is very risky, especially for retirement savings. Most new businesses fail, so this is not a reliable strategy for long - term retirement income growth.

So, enrolling in a 401k and investing in the stock market is the best option.
