Final answer:

To find next year's population with a 3.1% growth rate, multiply the current population of 119,000 by 1.031, giving a result of 122,689, rounded to the nearest individual.

Step-by-step explanation:

To calculate next year's population of the city with a current population of 119,000 and an annual growth rate of 3.1%, we use the formula for exponential growth: future population = current population × (1 + growth rate). Here, the growth rate is 3.1%, or 0.031 when expressed as a decimal.

So, the future population = 119,000 × (1 + 0.031) = 119,000 × 1.031.

After performing the multiplication, we get a result of future population = 122,689.

Therefore, next year's population is expected to be 122,689, rounded to the nearest individual.

Answer:

the next year population is 122,689

Step-by-step explanation:

The computation of the next year population is as follows:

= This year population × increase percentage

= 119,000 × (1 + 0.031)

= 119,000 × 1.031

= 122,689

Hence, the next year population is 122,689

The above formula is applied so that the correct value of the population could come
