If a town with a population of 7,000 doubles in size every 72 years, what will the population be 144 years from now?

Question

Im still stuck in these questions 

Answer 1

Hi Jose,

First, we need to know how many doublings will occur by determining how many times 72 can fit into 144.

144/72 = 2

So that means that the town's population will double twice.

Let's take this one doubling at a time.

 

After the first 72 years, the population of 7,000 will go to 14,000 (we found this out by multiplying 7000*2).

 

Now the population is 14,000, and we have another 72 years to go.

So again, we'll double the population (14000*2) to realize the population is 28,000.
