Komiko tanaka invests $19,500 in lymabean, inc. lymabean does not pay any dividends.

$29,619

Explanation:

Given that,

Investment = $19,500

Investment will generate(r) = 10 percent before-tax rate of return

Tenure = 5 years

                                                              = $19,500 × 1.61051

                                                              = $31,404.945

Basis in stock = $19,500

Long term capital gain = Amount received - Basis in stock

                                      = $31,404.945 - $19,500

                                      = $11,904.945

Tax on gain = Long term capital gain × rate

                    = $11,904.945 × 15%

                    = $1,785.74

Cash retained = Amount received - Tax on gain

                        = $31,404.945 - $1,785.74

                        = $29,619.205

                         = $29,619

Therefore, $29,619 cash will Komiko retain, after-taxes.
