If in 2014, the Australias population was 23 246 692, with a growth rate of approximately 1.14%, what was the population in 2015?

Please help! What is the formula and how would you work out this question

The answer would be 23,246,692*(1.0114) = 23511704.29.

Rounding to the nearest integer (since we can't have fractional people), answer is 23511704.

Because there is a population growth, it would be 23246692*(1+0.0114) = 23511704.29 (2 dp.)

Because people are in a whole, the answer is 23511704.

BONUS

Just say there is a population decline, it would be 23246692*(1-0.0114) = 22981679.70 (2 dp.)

Because people are in a whole, the answer is 22981679.

The formula is to turn the percentage to an actual number. For example, 2% of 100 people is 2 people. If in 2014 there are 100 people and in 2015 there was a 2% growth, it would be (100 people)X(2 percent to a whole number is 0.02, but since it's a growth it's 1.02) = 102.
