Question

To find the population of a city next year, we multiply its current population by 0.971. By what percent does the population decrease per year?

Answer 1

To find the percent decrease in population per year, multiply the difference between the current population and the next year's population by 100.

Step-by-step explanation:

To find the percent decrease in population per year, we can use the formula: percent decrease = (1 - 0.971) * 100. This formula calculates the difference between the current population (1) and the next year's population (0.971), and then converts it into a percentage.

For example, if the current population is 100, the population next year would be 100 * 0.971 = 97.1. The percent decrease would be (1 - 0.971) * 100 = 2.9%. So, the population decreases by 2.9% per year.
