Farmer Langa starts farming with 450 sheep. He finds that his stock increases by 12% each year. How many sheep will Langa have on his farm at the end of 5 years?

If the stock increases by 12% each year, then we'll have to multiply it by 5 to find out the increase in five years.

So,

12 x 5 = 60

Now we know that there will be an increase of 60% after 5 years. Now we will turn the percent into a decimal and multiply it by the amount of sheep (450)

So,

60/100 = 0.6

0.6 x 450 = 270

Since there is a 60% INCREASE we will add 270 to 450.

So,

450 + 270 = 720

Therefore, Langa will have 720 sheep after five years.
