The correct answer is B.

Let M be Michael’s money and J be Jackson’s money. Therefore:
M + J = 2200 and 3M \(= \frac{2}{3} J →M = \frac{2}{9} J\)
Replace the value of M in the first equation with its value in the second equation.
\(\frac{2}{9} J + J = 2200→ J = 1800\)
\(M = \frac{2}{9} J → M = \frac{2}{9} (1800) = 400\)
Michael has $400.
