Answer:
3787000
Explanation:
360*1/9=40 - skilled workers
360-40=320- the quantity of unskilled
6*13500=81000- wage for six unskilled
(320-6)*9000= 314*9000= 2826000- wage for the rest of unskilled
2826000+81000= 2907000- wage for unskilled
40/2=20 - the half on skilled
20*19500= 390000- Payment for a half
20*24500= 490000- Payment for ANOTHER HALF OF SKILLED WORKERS
2907000+390000+490000= 3787000
