Diane Van Os decided to buy a new car since her credit union was offering such low interest rates. She borrowed $32,000 at 3.5% on December 26, 2012, and paid it off February 21, 2014. How much did she pay in interest?(Assume ordinary interest.)

1 answer

First, we need to determine the term of the loan (how long she had the loan). To do this, we subtract the start date of December 26, 2012, from the pay-off date of February 21, 2014.

2014 - 2012 = 2 years
February - December = 2 months
21 - 26 = -5 days

So, the total term of the loan was 2 years, 2 months, and 5 days.

Now we need to convert this to the number of days:
2 years x 365 days/year = 730 days
2 months x 30 days/month = 60 days
Total days = 730 + 60 + 5 = 795 days

Next, we'll calculate the interest. The formula for calculating ordinary/simple interest is:

Interest = Principal x Rate x Time

In this case:
Principal = $32,000
Rate = 3.5% = 0.035
Time = 795 days

First, we need to convert the time to a fraction of a year:
Time (in years) = 795 days / 365 days/year = 2.1753 years

Now, we can calculate the interest:

Interest = $32,000 x 0.035 x 2.1753
Interest = $2,446.70

Diane Van Os paid $2,446.70 in interest on her car loan.
