Find the future value of an ordinary annuity if payments are made in the amount R and interest is compounded as given. Then determine how much of this value is from contributions and how much is from interest. R=15,000; 4.7% interest compounded quarterly for 8 years. 2. Find the interest rate needed for the sinking fund to reach the required amount. Assume that the compounding period is the same as the payment period. $24,751 to be accumulated in 5 years; quarterly payments of $1075. Find the periodic payment which will amount to a sum of $ 21000 if an interest rate 5% is compounded annually at the end of 8 consecutive years. Find the size of each of 8 payments made at the end of each year into a 8% rate sinking fund which produces $14000 at the end of 8 years. Find the amount of each payment to be made into a sinking fund earning,7%i compounded monthly to accumulate $89,000 over 8 years. Payments are made at the end of each period
