 In this video, we provide the solution to question number eight from practice exam two from math 1050, in which case we have a simple interest problem here. $875 is borrowed by you for four years at a rate of 4.28 APR annual percentage rate. So how much is due back at the end of the four years? So we're going to use our simple interest formula. The amount that's due back will be principal times one plus RT where P is our principal. So that would be $875 one plus the rate. This was a percentage we need to write as a decimal here point zero four to eight and any times that by the years, which is four. And then feel free to use a calculator at this moment. You're going to get four times, like I said, the 4.28%. Check with your calculator with that one, you'd end up with, we're going to carry this over here, you're going to get one plus the 17, I should say 0.172. So that will just add with the one so we get the 1712 right there. And so then we need a times that by the 875. And we end up with 1024.8. So 80 cents there. So we see the collect correct answer be F. So this is just a basic application of simple interest.
