Answer:
$2880
Step-by-step explanation:
I = Prt
= $3600·8%·10 = 0.80·$3600 = $2880
The simple interest on $3600 over a 10-year period is $2880.
Given:
The equation is:
To find:
The solution for the given equation.
Solution:
We have,
It can be written as:
Taking square root on both sides, we get
[Radius cannot be negative]
