Measurements are made at two different times. Find the absolute change and then find the relative change. Round answers to the nearest
The population of Placerville grew from 4,220 a decade ago to 7,220 today.
To find the absolute change, subtract the initial measurement from the final measurement.
Absolute change = Final measurement - Initial measurement
Population change = 7,220 - 4,220 = 3,000
To find the relative change, divide the absolute change by the initial measurement and multiply by 100 to get the percentage change.
Relative change = (Absolute change / Initial measurement) * 100
Relative change = (3,000 / 4,220) * 100 ≈ 71.09%
Thus, the absolute change in population was 3,000 and the relative change was approximately 71.09%.
