Measurements are made at two different times. Find the absolute change and then find the relative change. Round answers to the nearest

Question

The population of Placerville grew from 4,220 a decade ago to 7,220 today.

Answer 1

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%.
