The following group of values was entered into the TVM solver on a graphing calculator

Kisachek [45]

Based on the entries into the TVM solver, the expression that will return the same value for PV is $\frac{(620) (( 1 + 0.066)^{108} - 1) }{(0.066) (1 + (0.066))^{108}}$ .

<h3>Which formula will give the same Present Value?</h3>

The formula for present value for this series of cashflows is:

= $\frac{(Payment) (( 1 + Interest rate)^{Number of years} - 1) }{(Periodic interest) (1 + (Periodic interest))^{Number of years}}$

Based on the P/Y and the C/Y being 12, the number of periods given in the graphing calculator will be the same in the formula, which is 108 periods.

The interest rate of 6.6% will also be the same in the formula.

The best option is therefore option B which has all these figures and so will give the same present value.
