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 <u>option B </u>which has all these figures and so will give the same present value.

a³ + b³ = (a + b)(a² - ab + b²), thus

27x³ + 64

= (3x)³ + 4³

= (3x + 4)(9x² - 12x + 16)
