The simple interest is 3.80% per year.

Step-by-step explanation:

We are presented with a simple interest problem and the following information has been availed;

Accumulated amount = 5503.51

Time = 19 years

Principal = 3196

The first step is to determine the total interest earned over the entire time period;

Interest = Amount - Principal

             = 5503.51 - 3196

             = 2307.51

The simple interest formula states the total interest earned is equal to the product of the principal, the interest rate and the time;

Making R the subject of the formula yields;

Substituting the values we have and simplifying;

The simple interest is thus 3.80% per year.
