Question 83408
Let x=number of employees in aerospace div
Any y=number of employees in Ag div

Now we are told that:

x+y=3000-----------------------eq1

We are also told that:

0.10x+0.15y=0.12(3000)-------------------eq2

Multiply eq1 by 0.10 and we get:

0.10x+0.10y=300  now subtract this eq from eq2 and we have

0.05y=60  divide both sides by 0.05

y=1200-------------------number of employees in the ag div

from eq1, x=3000-y;  x=3000-1200;

x=1800-------------------------number of employees in the aero div

ck
0.10(1800)+0.15(1200)=0.12(3000)

180+180=360
360=360


Hope this helps----ptaylor
