High$-$Low Method for a Service Company

Boston Railroad decided to use the high$-$low method and operating data from the past six months to estimate the fixed and variable components of transportation costs. The activity base used by Boston Railroad is a measure of railroad operating activity, termed "gross$-$ton miles," which is the total number of tons multiplied by the miles moved.

$\backslash$table$[[,$Transportation Costs,Gross$-$Ton Miles$],[$January$,$$$919,100,334,000],[$February$,1,024,700,373,000],[$March$,724,200,242,000],[$April$,982,500,362,000],[$May$,824,000,291,000],[$June$,1,056,400,393,000]]$

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