Final answer:
Carl may contribute to a Roth IRA but not a traditional IRA.
Step-by-step explanation:
Carl is not eligible to contribute to a traditional IRA because he has no earned income. However, he can contribute to a Roth IRA because the contributions are made after taxes. Since Carl makes about $10,000 a year from interest and dividends, he can use this income to contribute to a Roth IRA.
Example: If Carl contributes $5,000 to a Roth IRA, his taxable income remains at $10,000. However, if he had contributed to a traditional IRA, his taxable income would have been reduced by the contribution amount.
In conclusion, the statement is True:
Carl may contribute to a Roth IRA but not a traditional IRA.
