Jonah is self$-$employed with net self$-$employment income of $$50,000$ per year. His wife was eligible for a family health insurance policy through her employer for the entire year, but she declined that insurance in favor of a plan that she and Jonah got on their own. They pay $$400$ per month for health insurance that covered them both. What is the total amount of health insurance premiums that Jonah can use to compute the SELF$-$Employed Health Insurance deduction?
