Answer:
1.
$9,000 x ((1+0.0435)^3) = $10,226.33
$3,000 x ((1+0.0375)^3) = $3,350.31
(($4,000 x (1+0.08))x (1-0.04)) x (1+0.06) = $4,396.03
$4,000 x ((1+0.029)^3) = $4,358.19
2.
$22,330.87 - $20,000 = $2,330.87
3.
$4,000 x ((1+0.0435)^3) = $4,545.04
$3,000 x ((1+0.0375)^3) = $3,350.31
(($9,000 x (1+0.08))x (1-0.04)) x (1+0.06) = $9,891.07
$4,000 x ((1+0.029)^3) = $4,358.19
Total Gain on new split: $22,144.61 - $20,000 = $2,144.61
