Question

Richmond County has a population of 850,000 people, which increases by 10% every year

due to a growing tech industry. What will the population be in 2 years?
If necessary, round your answer to the nearest whole number

Answer 1

1,028,500 people

Explanation:

When finding the percentage of a number you moved the decimal place over twice and then multiply.

850,000 x 0.10 = 85,000

10% of 850,000 is 85,000

I then found the population of the 1st year

85,000 + 850,000 = 935,000

then I found 10% of that 1st year

935,000 x 0.10 = 93,500

then added 85,000 and 93,500 to find the population growth in the 2 years

85,000 + 93,500 = 178,500

Then added the population growth to the original population

178,500 + 850,000 = 1,028,500 people

(I'm sorry, my last answer was wrong)

Hope this helps! :)

Answer 2

If the current population is 850,000. Next year it will be 935,000, and the year following that it will be 1,028,500. This is a linear growth (its growth has a common ratio).
