There are 30 000 zebras in Horadina. The number of zebras decreases by 4% each year due to poaching. Each year 5 000 zebras are born, but 1 500 die in infancy.

Write a difference equation to describe this, stating clearly the terms you use.

Any help would be appreciated!

Is the answer Sn+1 = 1.04(Sn) + 3640, S0= 30 000, N=1,2,3...?
