Quizplus · Accepted Answer

To predict the population of the city in 10 years with a 2% annual decrease, we use the formula for exponential decay: P = P0(1 - r)^t, where P0 is the initial population, r is the rate of decrease (as a decimal), and t is the time in years. Plugging in the values: P = 170,000(1 - 0.02)^10 ≈ 138,902 when rounded to the nearest whole number.
