Answer:
a. $5,500
b. $5,500
Step-by-step explanation:
During 2016, the maximum contribution per person was $5,500 ($6,500 if older than 50) or 100% of taxable income, whichever is lower. Since both spouses work, they can both contribute to their own IRA accounts. Assuming that they file their taxes jointly, then they can both contribute the maximum amount (it doesn't matter who earns more money) since their combined AGI is higher than $11,000.
