The term "Interest Cost" refers to the amount of money that is paid in interest for borrowing money or using credit. It is the additional amount that must be paid on top of the original loan or credit amount.

2. Who is Reza D. and why is their interest cost being mentioned?

Reza D. is an individual who has borrowed money or used credit and is now being charged interest on that amount. Their interest cost is being mentioned because it is a significant factor in determining the total amount that must be repaid.

4. How is the interest cost calculated?

The interest cost is calculated by multiplying the original loan or credit amount by the interest rate (18¾% in this case) and then dividing by the number of periods in a year. This will give the amount of interest that must be paid for one year. This amount is then multiplied by the number of years the loan or credit is held to determine the total interest cost.
