Answer 1

Answer:

$245.09

Explanation:

A service contract for a video projection system costs $90 a year. You expect to use the system for three years.

Instead of buying the service contract, the future value of these annual amounts after three years if you earn 5 percent on your savings will be:

PV  

Ordinary Annuity

​  =C×[  ((1−(1+i)  ^−n ) / i ]

where

n = number of years = 3

i = interest rate = 5%

Present Value of the annuity = 90 x [ ((1 - (1+0.05)^-3) / 0.05] = $245.09
