Understand Percentage Decrease: Understand the percentage decrease. A 2% decrease means that the population will be 2% less than the current population.
Convert to Decimal: Convert the percentage decrease to a decimal.To find the new population, we subtract 2% (as a decimal, which is 0.02) from 1 (which represents the whole population).1−0.02=0.98
Apply Decrease to Population: Apply the decrease to the current population.To find next year's population, we multiply the current population p by 0.98.Next year's population = p×0.98
