Any number raised to the power of 0 is 1.
Therefore, 15^0 = 1
2+x=2x-15
>> 2+15=2x-x
>> 17 = x
So the answer is <u>17</u>
Given parameters:
Current population = 530,300 people
Growth rate = 0.8% per year
Unknown
Population in 15 more years = ?
To solve this problem, we must compound the increase per year.
This implies that we treat the problem like that of a compound interest.
Since we know that population increases by 0.8%,
it is similar to 1 +
= 1.008 increase
Now the population in 15years will be;
530300 x (1.008)¹⁵ = 597626 people
So, the population after 15yrs is 597626 people
