To begin lets say year one the population is 2,000
assume this in percent we can say that 2,000=100%
at the end of this year the population will have grown by 4% meaning that
100%+4% will be the new population =104%
but we know that 100%=2,000 so what about 104%=X?
so (104*2000)/100=2,080
So year 1 the population will have grown by 80 people amounting to 2080 people.
Now do it manually year by year until we reach the 15th year. i will help you up to year 3
2nd year= (2080*104)/100=2163.2
3rd year= (2163*104)/100=2249.728

Answer: 1200
Step-by-step explanation:
Answer:
The full Question is attached in the picture below.
PR = 5(9) +28 = 73
Step-by-step explanation:
Since the figure is a rectangle
SQ = PR
11x-26 = 5x +28
6x = 54
x = 9
2x + y = 20
y = 20 - 2x
Substitute into second equation:
6x - 5(20-2x) = 12
6x -100 +10x = 12
16x = 112
x = 7
Plug back into first equation:
2(7) + y = 20
14 +y = 20
y = 6
Answer is x = 7 and y = 6
