25 kids in all
2xboys:3x girls
so the equation would be
2x+3x=25
solve,
5x=25
/5 /5
x=5
2x=10
3x=15
10 boys and 15 girls
An exponential model is used to represent growth of a population
The population after 3 years is 2585
The function is given as:
![\mathbf{P(x) = 2400(1.025)^x}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%28x%29%20%3D%202400%281.025%29%5Ex%7D)
<em>3 years after</em>, means that x = 3
So, we have:
![\mathbf{P(3) = 2400(1.025)^3}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%283%29%20%3D%202400%281.025%29%5E3%7D)
Evaluate exponents
![\mathbf{P(3) = 2400 \times 1.076890625}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%283%29%20%3D%202400%20%5Ctimes%201.076890625%7D)
![\mathbf{P(3) = 2584.5375}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%283%29%20%3D%202584.5375%7D)
Approximate
![\mathbf{P(3) = 2585}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%283%29%20%3D%202585%7D)
Hence, the population after 3 years is 2585
