The original ratio of Muki's to Mushi's investment is 21,000:37,000 or 21:37. After Muki invests an additional $9,000, his total investment becomes $30,000. To maintain the original ratio, Mushi's investment should be 30,000 * (37/21) = $52,857.14. Therefore, Mushi should contribute $52,857.14 - $37,000 = $15,857.14.
