Answer:
THe expected annual cost is $282200
Step-by-step explanation:
We should take the base cost and sum it by the anual cost multiplied by 3, because the lifetime of the machines is 3 years. Since the expected return is 10%, then we have to multiply the result by 1.1, therefore
cost = (750000+12000*3)*1.1 = $864600
Now, we divide this by 3 to obtain the annual cost
Annual cost = 864600/3 = $288200

Step-by-step explanation:
We are given that
Area of pasture,A=180000 square meter
We have to find the least amount of fencing required to enclose such a pasture.
Let length of pasture,=x
Width of pasture,b=y
Area of pasture=
Fencing required=2x+y
Differentiate w.r.t x
m
It is always positive because length cannot be negative.
m
Again differentiate w.r.t x
Substitute x=300
The fence is minimum at x=300
Therefore, fencing required to enclose such a pasture
