The Chart Below Shows the Amount Spent by Three U

The chart below shows the amount spent by three U.S. airlines to fly one available seat one mile in the fourth quarter of 2000. $\begin{array} { | l | l | l | l | } \hline \text { Airline } & \text { Continental } & \text { SkyWest } & \text { SouthWest } \\\hline \text { Cost } & 9.8 \text { cents } & 20.3 \text { cents } & 7.8 \text { cents } \\\hline\end{array}$
