Answer:
About 473 quails.
Step-by-step explanation:
Exponential equation with as the initial amount and rate of r is:
After 5 years the population will be:
So the population will be about 473 quails.
f/p = p(1+i)^n
p= 2500
i=0.03 =3%
n=4
2500(1 + 0.03)^4
x=20
180=2x+6x+20
180=8x+20
160=8x
20=x
the price was reduced by 28%
