Three years later, they opened a new account for him. They deposited $5000 to this new account and transferred over the balance om the original account. The new account paid interest at 4.95% compounded daily. How much money was originally invested if Harpreet had $15 000.67 in the account on the day he turned 19? 2. A variable rate demand loan showed an initial balance of $9000, payments of $2500 after 6 months, $2500 after 21 months, and a nal payment after 4 years. Interest was 8% compounded quarterly for the rst 21 months and 7.75% compounded monthly for the remaining time. What was the size of the nal payment? 3. Four years and 7 months before its due date, a seven-year note for $2650, bearing interest at 9% compounded quarterly, is discounted at 8% compounded semi-annually. Calculate the compound discount. 4. Scheduled payments of $1200 due one year ago and $1000 due six months ago are to be replaced by a payment of $800 now, a second payment of $1000 nine months from now, and a nal payment 18 months from now. What is the size of the nal payment if interest is 10.8% compounded quarterly? 5. Scheduled payments of $900 due in 3 months with interest at 11% compounded quarterly and $800 due in 30 months with interest at 1 1% compounded quarterly are to be replaced by two equal payments. The rst replacement payment is due today and the second payment is due in three years. Determine the size of the two replacement payments if interest is 9% compounded monthly and the focal date is today
