Answer:

3570

Step-by-step explanation:

We use percentage formula here:

Beginning Amount * Percentage = Final Amount

Plug in the values

3200 * 15/100 = Final

480=  Final

Now we have 480 ppl growth from 97 to 07, so we have 3680 people

3680 * 3/100= Final

110.4= Final

110=Final

(Rounded)

Now that we decreased, we subtract 3680-110 and get the final population of 3570

We are given two metrics to work with: 10 years of time, and population change. The base is 3200 people at 1997. Ten years later, 3200 is increased to 3680 people, presumably due to living conditions improving. Another ten years later, the town's situation is stagnating. The population decreases somewhat, dropping down to 3569.6. This is because someone lost an arm and a leg, decreasing their person status to 60%.
