Answer:

1 - Since the interest rate is compounded semi-annually and the payments are monthly, we must adjust one to match the other.

2 - Generally, the easiest way is to to adjust the interest rate from semi-annual compounding to monthly compounding.

3 - 9% = 0.09 / 2 =0.045 + 1 =1.045^(1/6) =1.00736312 - 1 x 12 x 100 =8.836% compounded monthly.

4 - PV=0; PMT=3000; R=0.08836/12; N=6; PV==PMT*(((1 + R)^N - 1)*((1 + R)^-N)* R^-1)

5 - PV==17,545.08 - the cost of the TV
