What is the formula for borrowing $5000.00 for one year $100.00 interest 
what is the interest rate and how much paid at end of the year?

<pre>
The formula for the interest rate is  

    r = {{{100/5000}}} = {{{1/50}}} = 0.02 = 2%.


The amount to pay back at the end of the year is $5000 + $100 = $5100.
