Aw you put the numbers in so a b c then you solve
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
The answer is (4x+3y=4 2x-7=7: 5/2 and y=-2) hope it helps and have a good day!
13 should be b and
14 is a because geometric mean to have a common ratio
