Okay i haven't done this years but base on my knowledge it think that the answer is 6 and that because:
(2x+3) + (3-2x)
(2x+2x+3) +(3-2x+2x)      (what ever you to one side you do the next and that why it cancel each other)
3+3=6

What is the PV of an ordinary annuity with 10 payments of $2,700 if the appropriate interest rate is 5.5%? Group of answer choic
Verizon [17]

Answer:

The PV of an ordinary annuity with 10 payments of $2,700 if the appropriate interest rate is 5.5% is $20,352.

Step-by-step explanation:

P = PMT [(1 - (1 / (1 + r)^{n})) / r]

= 2,700 [(1 - (1 / (1 + 0.055)^{10})) / 0.05]

= 2,700 [(1 - (1 / (1 + 0.055)^{10})) / 0.05]

= 2,700 [(1 - (1 / (1.708)) / 0.05]

= 2,700 [(1 - 0.58)) / 0.05]

= 2,700 [(0.41457) / 0.05]

= 2,700(7.53)

=$ 20,352
