General formula to be used: 
F = future worth; P = present worth, i = annual interest, n = years
1.)
F = <span>$5931.06
</span>
2.)
i = 2.43%
3.)
n = 3.7 = 4 years
4.)
F = $329.39
5.)
P = $1.45
*I doubt the 1212 years. I think that is a typo error. Nevertheless, just substitute the correct number of years to determine P :)
