You can put this solution on YOUR website!
This is kind of difficult because we don't know the length of time.
Yet, to get the interest rate you would
%2445%2F%241500=x%2F100
4500=1500x
3%25=x
%242000x0.3=%246.00
To get the interest over a period of time you would use
I=PRT or Interest=principle x time x rate. We don't have the time period.
I hope that helps you.
