1.2.9 Annuity Free Response Question
An annuity is a financial account that produces a fixed payment to the account's owner every year until the
funds in the account are gone. The present value of an annuity is calculated using the amount of the
payment, the interest earned, and the number of payments that will be made.
Specifically, the present value (PV) of an annuity at the time it is created can be determined with the following
formula
PV = pmt
Where: pnt is the payment amount
1 is the interest rate
n is the number of payments to be made
An incomplete Annuity class is provided
public class Annuity
/
• Returns the present value of the annuity
./
public double getPresentValue(int pmt, int i, int n)
to be implemented /
}
// there may be instance variables, constructors, and methods not shown
}
FRQ Using the method header below, write the method getPresentValue. You must convert the given
interest value i to an interest rate percentage.
public double getPresentValue(int pmt, int i, int n)
