In 2016, Alberta had about 4.2 million people. Assuming they follow the same population growth rate, it is predicted they will have 6.65 million people in 20 years. At what rate is the province's population growing?
Answers
Answer:
58 1/3 %
Step-by-step explanation:
Put the differences of the two populations (2,450,000) over the actual population (4,200,000) and multiply the output by 100 to get the percentage grown
Answer:
The rate at which the population has increased is 53.6%
Step-by-step explanation:
Given,
In 2016, Alberta had about 'p' = 4.2 million people.
After 20 years i.e. by 2036 the population of Alberta is 'P' = 6.65 million.
To find,
The rate at which the population has increased Δp%.
Calculation,
We try to find the increase in population from the year 2016 to 2036.
i.e. P - p = 6.65 million - 4.2 million = 2.25 million.
Now the percentage in the increase or the rate at which it has increased is:
Δp% = (P - p)/p × (100)
Δp% = 2.25 million/4.2 million × (100)
Δp% = 0.536 × 100
Δp% = 53.6 %
Therefore, the rate at which the population has increased is 53.6%
