How much does it cost to watch a complete 21-hour-long World Series on a 180-W television set? Assume that electricity costs $0.070/kWh

3. The attempt at a solution

[tex] \frac {0.070}{kWh} = \frac {x}{(180*10^{3}kW)(21h)}[/tex]

[tex] \frac {0.070*(180*10^3 kW)(21h)}{kWh} = x [/tex]

I got $264,600 when the answer is suppose to be 26 cents. What am I doing wrong here? Thanks.
