Answer:
you can cross multiply or u can 7/20 to get the answer that 7 is 35% of 20
You first must find the 18% of the fish population.
You multiply 500 by .18 . You are supposed to get 90.

Answer:
You have to use the formula for compound interest which is: A=P(1+r/n)^nt
The Givens info is:
A=?
P=1000
r= 6% = 0.06 (convert into decimal)
n=12(# of interest periods: since it is monthly n=12)
t=10
Now your formula should look like this:
A= 1000*(1+(0.06/12))^12*10
A=1000*(1.005)^120
A=1000*(1.819396734)
A=$1819.40
