Question

A rabbit population starts with 10 rabbits and doubbles each year for three years. How many rabbits will be there at the end of the three years?

Answer 1

We know that

• The population starts with 10 rabbits.

,

• The population doubles each year for three years.

To find the answer, we just have to multiply.

Notice that the population has to start with 10 rabbits, from there we double each year. Now, we sum all the rabbits in total.

`10+20+40+80=150`

Therefore, after three years there are 150 rabbits.
