A wildlife preserve is being planned for 3,000 rhinoceroses. The preserve is to contain a total of 10,000 acres of watering area, plus 100 acres of grazing area for each rhinoceros. If the number of rhinoceroses is expected to increase by 10 percent, how many thousand acres should the preserve have in order to provide for the increased population?
Please show your work.
Well, make an equation in the form of a line:
y=mx+c; c=10000, x=3000 and m=100 y is a required preserve
bcoz there is one not changing part i.e. watering area and one part which is changing i.e. no of rhinoceroses.
y=3,10,000 in first case.
Now, if rhinoceroses will become 3300 then,
y=3300*100+10000 =3,40,000 = 340 thousands (A) is the answer
Hope this helps, Dharmin
