Problema Solution

Myerson borrowed $8,500 at 9% ordinary interest for 200 days. After 120 days, he made a partial payment of $4,000. What is the final amount due on the loan?

Ordinary interest is calculated on the basis of a 360 days per year.

Interest due at the end of 120 days
= 8500(120/360)(0.09) = $255

Of the $4000 payment, $4000 - $255 = $3,745 will go towards reducing the debt.
so balance owing = 8500 - 3745 = $4755

Interest for the remaining 80 days
= 4755(0.09)(80/360) =95.10

The final amount due on the loan = 4755+95.10 = $4,850.10.
