A, B and C, each working alone can complete a job in 6, 8 and 12 days respectively. If all three of them work together to complete a job and earn $2200, what will be C's share of the earnings?	Choose the correct choice from the following.
A) $488.9 B) $480.9 C) $588.9 D) $680.9 E) $788.9
The dollars earned will be in the same ratio as amount of work done   1 day work of C is 1/12 (or 2/24)   1 day work of the combined workforce is (1/6 + 1/8 + 1/12) = 9/24   C's contribution is 2/9 of the combined effort   Translating effort to $ = 2/9 * 2200 = $488.9   hence:$488.9
