Continental 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 Continental Railroad is a measure of railroad operating activity, termed "gross-ton miles," which is the total number of tons multiplied by the miles moved.

	Transportation Costs		Gross-Ton Miles
January	$547,800		243,000
February	610,700		272,000
March	431,600		176,000
April	585,500		263,000
May	491,100		212,000
June	629,600		286,000

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