Answer:
A) they should work on their plan for managing income.
Explanation:
They are currently spending too much money and they should either lower their costs or Jackie will have to find a job:
total monthly expenses = $2,800 (mortgage and extras) + $2,700 other expenses = $5,500 x 12 months = $66,000
Since Jim contributes 15% of his income to a retirement fund, they are currently having a deficit = net income - total expenses = ($67,000 x 85%) - $66,000 = $56,950 - $66,000 = -$9,050
They will not to able to handle this deficit for a long time, so they should decide which expenses to cut (out of the $2,800 additional expenses).
