Question

The population of a city was 500,000 last year. This year, it increased to 550,000. What is the percent increase in population?

a) 5%
b) 8%
c) 10%
d) 15%

Answer 1

The percent increase in population from 500,000 to 550,000 is calculated by subtracting the original population from the new population, dividing that result by the original population, and then multiplying by 100. The percent increase is 10%, corresponding to option c).

Step-by-step explanation:

To calculate the percent increase in population, you need to subtract the original population from the new population and then divide that number by the original population. Finally, you multiply by 100 to get a percentage.

So in this case, the calculation would look like this:

1. Subtract the original population from the new population: 550,000 - 500,000 = 50,000.
2. Divide that number by the original population: 50,000 ÷ 500,000 = 0.10.
3. Multiply by 100 to get a percentage: 0.10 × 100 = 10%.

Therefore, the percent increase in the population from 500,000 to 550,000 is 10%, which corresponds to option c).
