Q. To find the population of a city next year, we multiply its current population by 0.981 . By what percent does the population decrease per year?Answer: ______ %
Understand Population Decrease: First, we need to understand that multiplying the population by 0.981 means the population is 98.1% of its original size. To find the percent decrease, we need to calculate how much less this is than 100%.
Calculate Percent Difference: Subtract the percentage that represents the new population size (98.1%) from 100% to find the percent decrease.100%−98.1%=1.9%
Determine Annual Decrease: The percent decrease in the population per year is therefore 1.9%.
