Answer:
The population in 10 years will be approximately 358,528.
Explanation:
I'm making a table where it shows the population every year. To find how much there is that year, I multiply the previous step by 1.02, which is 102%.
(I'm multiplying by 1.02 (102%) rather than 0.02 (2%) because the population is the previous year's population plus 2%. The previous year's population is 100%, then I'm adding 2%.)
Here's what it would look like:
year 0: 300,000 (this is how the city starts)
year 1: 306,000
year 2: 312,120
year 3: 318,362.4
year 4: 324,729.648
year 5: 331,224.24096
year 6: 337,848.7257792
year 7: 337,848.7257792
year 8: 344,605.700294784
year 9: 351,497.8143006797
year 10: 358,527.7705866933
However, having 0.7705866933 of a person isn't possible, so now, you round to the nearest whole number. The number 358,527.7705866933 rounds up to 358,528 (because the decimal place is greater than 4).
And there you have your answer :) Hopefully this helps!
