Find the interest on a student loan of $5,000 at 3.5% for 5 years.

P is the principal amount, $5000.00.

r is the interest rate, 3.5% per year, or in decimal form, 3.5/100=0.035.

t is the time involved, 5year(s) time periods.

So, t is 5year time periods.

To find the simple interest, we multiply 5000 × 0.035 × 5 to get that:

The interest is: $875.00

Step-by-step explanation:I=P×r×t

I hope this helps
