Did they give you a formula for this?
That's what I kinda need help with. I think it's something like I=Prt, but I'm probably wrong. I'm really confused on what formula to use. :/
I think that's the right formula. Sorry it took me so long my computer spazzed out lol. There's also another formula for more complicated problems but I don't know that one, @hba might though.

You messaged after 10 min,Wow.
I already apologized for answering late, my computer had a spazz attack and I had to restart it, anyway that's not the point here.
I think I got the answer... I used the A=P(1+r/n)^nt formula and got the answer 3,546.50. Is that right, you think?
And it's okay, my computer spazzes all the time... lol. I know how it is. (:
