Answer: To find the percent increase in population, I used the following formula:
percent increase = (new value - old value) / old value * 100
In this case, the old value was the population from a decade ago (4360), and the new value was the current population (6590). So plugging these values into the formula, we get:
percent increase = (6590 - 4360) / 4360 * 100
percent increase = 51.38%
So the population of Placerville increased by approximately 51.38% over the past decade. The population of Placerville has increased by (6590 - 4360) = 2230 people over the past decade.
