The formula for this question is P(n) = P*(1+r)^n
So the initial population is 8600 or P, and n can be the number of years. r is the rate it grows, 3% or 0.03.
Plug in these values
P = 8600
r = 0.03
n = 3
into P(n) = P*(1+r)^n
1/4(12 + x)
3 + 1/4x
The solution is 3 + 1/4x
Answer:
x = 71/8
Step-by-step explanation:
Solve for x:
5 X (8 x - 71) = 0
Divide both sides by 5 X:
8 x - 71 = 0
Add 71 to both sides:
8 x = 71
Divide both sides by 8:
Answer: x = 71/8
