Question

The tree frog population in your back yard doubles every two weeks. Currently, there are 10 frogs in your back yard. Assuming that there are 4 weeks in a month how many tree frogs will there be in 3 months?

Answer 1

Here is how I solved, the answer is 640

Answer 2

Answer: There are 640 tree frogs would be in 3 months.

Step-by-step explanation:

Since we have given that

Population of frog becomes double in every two weeks.

There are 4 weeks in a month.

Initial population of frog=10

We need to find the number of tree frogs in 3 months.

Number of weeks in 3 months = $4\times 3=12\ weeks$

Number of two weeks in 12 weeks is given by

$\dfrac{12}{2}=6$

So, Number of tree frogs would be

$ar^n=10(2)^6=640$
