Q. To find the population of a city next year, we multiply its current population by

0

.

96

. By what percent does the population decrease per year?

\newline

Answer: ______

\%

Identify Original Population: To find the percentage decrease, we need to determine how much less the new population is compared to the original population. The original population is considered to be $100\%$ .
Calculate New Population Percentage: If the population is multiplied by $0.96$ , this means the new population is $96\%$ of the original population.
Find Percentage Decrease: To find the percentage decrease, we subtract the new percentage ( $96\%$ ) from the original percentage ( $100\%$ ). $\newline$ Calculation: $100\% - 96\% = 4\%$
Determine Annual Decrease Rate: The population decreases by $4\%$ per year.
