Find the simple interest if the principal is $360, rate is 6% and the time is 1 1/2 years
Simple interest formula: \(\displaystyle \,I\;=\;P\,\times\, r\,\times\,t\)
where: \(\displaystyle P\) is the principal amount of the loan.
\(\displaystyle \;\;\;\;\;\;r\) is the interest rate (per year)
\(\displaystyle \;\;\;\;\;\;t\) is the time of the loan (in years).
Therefore: \(\displaystyle \,I\;=\;\$360\,\times\,0.06\,\times\,\frac{3}{2}\;=\;\$32.40\)
