Answer:
P(t)=400000(1+0.05)^{t}
Explanation:
Certainly! The city's population increases at a steady rate of 5% per year. If the initial population is 400,000, you can use the following algebraic equation to represent the population after t years:

where:
P(t) is the population after t years,
is the initial population (400,000 in this case),
r is the growth rate (5% or 0.05 as a decimal), and
t is the number of years.
So, the algebraic equation for the given population pattern is:

This equation allows you to calculate the population after years (t) into the future.
