Final answer:
Rick's for AGI deduction for health insurance is limited to his net earnings from self-employment of $3,500, which is the total deduction he can claim for health insurance expenses.
Step-by-step explanation:
Rick is a self-employed carpenter who had net earnings from self-employment of $3,500. Over the last year, he paid $325 per month for health insurance. To calculate Rick's for AGI deduction for health insurance, we multiply $325 by 12 months to get $3,900
However, this amount cannot exceed his net earnings from self-employment, which are $3,500. Therefore, Rick's for AGI deduction for health insurance is $3,500, which corresponds to the total net earnings from his self-employment.
