Question

Suppose the population of a certain city is 4252. it is expected to decrease to 3393 thousand in 50 years. find the percent decrease.

Answer 1

We have to find out by how much the population decreased.

4252-3393 = 859

Now, we have to find out what percentage of 4252 is 859. To this, we divide 859 by 4252, and we get about 0.20 (rounded to nearest 100th).

This means that the expected percentage decrease is about 20%

Hope this helps!
