(C) Let the number of remaining workers be $x$.The total salary of all workers is the sum of the salaries of the technicians and the remaining workers.Using the formula for average: $	ext{Average} = \frac{	ext{Total Sum}}{	ext{Number of items}}$.$\frac{7 	imes 15000 + x 	imes 9000}{7 + x} = 12000$Multiply both sides by $(7 + x)$:$105000 + 9000x = 12000(7 + x)$$105000 + 9000x = 84000 + 12000x$Rearrange the terms to solve for $x$:$105000 - 84000 = 12000x - 9000x$$21000 = 3000x$$x = \frac{21000}{3000} = 7$The total number of workers is $7 + x = 7 + 7 = 14$.
