Question
One year, the population of a city was 152,000. Several years later it was 130,720. Find the percent decrease.
Solution
Step 1: Find the decrease in population. This is done by subtracting the final population from the initial population.
So, 152,000 (initial population) - 130,720 (final population) = 21,280 (decrease in population)
Step 2: To find the percent decrease, divide the decrease in population by the initial population and then multiply the result by 100.
So, (21,280 / 152,000) * 100 = 14% (percent decrease)
Therefore, the population of the city decreased by 14%.
