Question

The current population of a city is estimated to be 77, 435 people assume the city population Grows by about 1.05% per year predict the city population 22 years from now on round to the nearest whole number

Answer 1

To predict the city population 22 years from now, use the population growth rate of 1.05% per year. Calculate the annual population growth and multiply it by the number of years. Add this to the current population to find the predicted population.

Step-by-step explanation:

To predict the city population 22 years from now, we will use the population growth rate of 1.05% per year. First, we need to calculate the annual population growth.

Annual growth = current population x growth rate = 77,435 x 0.0105 = 812.19 people (rounded to the nearest whole number).

Next, we'll calculate the population after 22 years:

Population after 22 years = current population + (annual growth x number of years) = 77,435 + (812 x 22) = 95,419 (rounded to the nearest whole number).

Answer 2

97440

Explanation

To predict the city population in 22 years from now on, we shall use the population growth formula, which is

`\begin{gathered} P_n=P_0(1+r)^n \\ \text{Where P}_n\text{ = Predicted population in n years} \\ P_0=the\text{ current estimated population = 77435} \\ r=\text{population growth rate = 0.0105} \\ n=\text{ number of years = 22} \end{gathered}`

The predicted population in 22 years from now on is

`\begin{gathered} P_(22)=77435(1+0.0105)^(22) \\ P_(22)=77435(1.0105)^(22) \\ P_(22)=77435*1.25834287 \\ P_(22)=97440 \end{gathered}`
