High$-$low method for a service company

Sierra Railroad Inc. decided to use the high$-$low method and operating data from the past six

used by Sierra Railroad is "gross$-$ton miles," which is the total number of tons multiplied by the

miles moved.

Determine the variable cost per gross$-$ton mile and the total fixed cost.
