Answer 3

If we go here:
http://www.1728.org/compint2.htm
We can find the formula for finding the rate
log(1 + rate) = {log(total) -log(Principal)} ÷ Years

log(1+rate) = [log(388.50) - log(326.00)] / 10
log(1+rate) = [2.5893910231 - 2.5132176001] / 10
log(1+rate) = 0.0761734231 / 10
log(1+rate) = 0.0076173423

Since log (1+rate) = 0.0076173423
Then (10^0.0076173423) = 1+ rate
1.0176943005 = 1+rate
So,
.0176943005 = rate
rate = .0176943005 or * 100 =
1.76943005 %
