Answer:
Barry cannot contribute any amount to Roth IRA
Explanation:
For a single/ unmarried individual to be able to contribute to Roth IRA plan, his Adjustable Gross Income (AGI) should range between $117,000 and $132,000. Since Barry's annual income is $190,000, which is higher than the maximum AGI required for a single to be able to contribute to Roth IRA, he cannot contribute to Roth IRA.
