Question

The population of a Midwest industrial town decreased from 213,000 to 209,000 in just 2years. Assuming that this trend​ continues, what will the population be after an additional 3 ​years?

Answer 1

203,000

Explanation:

You need to find the pattern first, so you need to subtract 213,000 from 209,000 to get 4,000. Now that is the pattern for 2 years we need it for 1 year. So divide 4,000÷2=2,000 for 1 year. Next, you need to multiply 2,000×3=6,000. That is the decrease of the population for 3 years. Finally, subtract 6,000 from 209,000.

Hope you get an A! <3
