Electrical Energy and Power (Wrong because of decimal place)

Homework Statement

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

The Attempt at a Solution

$$\frac {0.070}{kWh} = \frac {x}{(180*10^{3}kW)(21h)}$$

$$\frac {0.070*(180*10^3 kW)(21h)}{kWh} = x$$

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

Why do you have 180*$$10^3$$kW?

Yes, you've converted your power the wrong way.
