<h3>What is rate of increase?</h3>
Rate of increase or decrease is defined as the increment or decrement in any quantity over a period of time constantly.
Here we have the data that:
There were 1500 birds in 2000 and they are decreasing at an annual rate of 6.5%.
a) If this trend continues, how many birds will be left by 2010
{1500x6.25}/{100}=97.5
So the bird decrement in the one year will be =97.5 so it will be in the 10 years or upto 2010 will be
97.5x10=975
So the birds left till 2010 will be:
Q=1500-975=525
b)The birds would there have been in 1990 will be:-
=1500+975=2475
Hence If this trend continues, how many birds will be left by 2010 will be 525.The birds would there have been in 1990 will be 2475

Answer:
$2,693.12 will the employee have eared at the end of 5 years.
Step-by-step explanation:
The formula of compound interest:
= A-P
A= The amount in the account after n years
P= Principal
r= rate of interest annually
n= time in years.
An employee put $5,000 in retirement account that offer 9% interest compounded annually.
Here P=$5,000, r=9%=0.09, n= 5 years
=$7,693.12
The interest = A-P
=$(7,693.12-5,000)
=$2,693.12
$2,693.12 will the employee have eared at the end of 5 years.
