Answer
Brief Explanations:
The present - value formula for a perpetuity is $PV=\frac{A}{r}$, where $PV$ is the present value, $A$ is the payment amount, and $r$ is the interest rate. Rearranging for $r$ gives $r = \frac{A}{PV}$, so the interest rate on a perpetuity can be calculated given present value and payment amount. The present - value and future - value formulas for an annuity due can be used to calculate their respective values. A perpetuity has no future - value concept in the traditional sense as it continues indefinitely.
Answer:
D. The future value of a perpetuity.
