Answer:
100
Step-by-step explanation:
dont know how to explain it.
The answer is 12.5 seconds.
48/5 = 120/x
x = 2.5
2.5 * 5 = 12.5
-18 + x = -11
Let's add 18 to both sides
x = 7
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
