Answer:The city’s population in 2025 will be 78,465.Step-by-step explanation:1. Let’s review the information given to us to answer the question correctly:Initial population in 2016 = 79,318

Annual decreasing rate = 0.12% = 0.0012

2. Estimate the city’s population in 2025.Let’s use the following formula for answering the question:P(x) = P₀ * (1 – r)ˣ, where:

P (x) represents the population after x years after 2016

P₀ represents the initial population

r represents the annual decreasing rate

x represents the number of years after 2016

Replacing with the real values, we have:x = 2025 – 2016

x = 9

P(x) = 79,318 * (1 – 0.0012)⁹

P(9) = 79,318 * (1 – 0.0012)⁹

P(9) = 79,318 * 0.9892517

P(9) = 78,465
