Answer:
$85,005.70
Step-by-step explanation:
To calculate the cost of the machine we must use the present value of an ordinary annuity. In this case, the interest charged was 11%, the payment was $23,000 a year and 5 yearly payments were made:
cost of the machine = payment x (present value ordinary 5 year annuity at 11%) = $23,000 x 3.69590 = $85,005.70
This is a simple way to determine the present value of a cash flow, much simpler than using an excel spreadsheet and the difference is insignificant, using the NPV function in excel you get $85,005.63.
