 In this video, we provide the solution to question number nine for practice exam four for math 1050, in which case we're going to do a interest problem here. How much money will you have to, excuse me, how much money will you have after three years? So this is going to be our T equals three here. If you invest $500 that sounds like principal at a rate of 8% annual interest rate. So this is our interest rate there at 8%. And then it's compounded quarterly. So that means n equals four. So using our standard formula, the amount is going to be P times one plus R over N to the N times T. So we have all this information here. The principal was 500. We have one plus we're going to get 0.08 over four and we raise that to the four times three. Now on this one, we're not actually looking for the specific number. We're just trying to set this thing up. So let's do try to simplify this a little bit. Four times three is 12. So the exponent should then be at 12. Four goes into 8.02 times. So you get one plus 0.02. So that's 0.1.02 there. 1.02 raised to the 12th. And so we see that would actually be choice G.
