The formula for simple interest for months is I=P * (r / m) * n. Where P is the principle and r is rate and m is the year or 12 months and n equals how many months.
I=300 * (0.068 / 12) * 6 = 10.2
So the interest would be $10.2
9618115-1013020 = 8605095
8605095/10 = 860509.5 per tick mark starting at 1,013,020
A = 3500(1 + .05/4)^ 4*10
= 36,783.08679
