EXAMPLE:
Old McDonald had a farm with three fenced in areas.
In the first area he kept 20 chickens and 15 cows.
In the second area he kept 25 chickens and 30 sheep.
In the three areas combined he keeps 100 chickens.
How many chickens did he keep in the third fenced area?
*****SOLUTION*****
3 fenced areas
20 chickens in area I
15 cows in area I
25 chickens in area II
30 sheep in area II
100 chickens total
Add 20 plus 25 and then subt. this sum from 100
100 - (20 + 25) = 55
Old McDonald kept 55 chickens in the third area.
