the computer costs 3030.
the payment is at the end of each month for 48 months.
the interest rate is 1.77 percent interest per month.

use a financial calculator to solve for this.
one such calculator can be found here:
http://arachnoid.com/finance/

your entries into the calculator are as follows:
present value = 3030
future value = 0
number of time periods = 48
payment amount = 0 or blank (you will solve for this)
interest rate percent per time period = 1.77
payment is at the end of the time period.

you then select pmt and your answer will be:
$94.22 due at the end of each month.

here's a picture of the calculator inputs and result.

$$$

your nominal interest rate is 12 * 1.77 = 21.24 percent per year.

your effective interest rate is 1.0177 ^ 12 - 1 = 23.4347 percent per year rounded to 4 decimal places.

1.0177 ^ 12 means 1.0177 raised to the 12th power.
