Identify the high and low points for each of the three measures.

		Passengers		Passenger miles		Train Miles
High point activity		enter the high point in dollars		enter the high point in dollars		enter the high point in dollars
High point $		$enter the high point in dollars		$enter the high point in dollars		$enter the high point in dollars
Low point activity		enter the low point in dollars		enter the low point in dollars		enter the low point in dollars
Low point $		$enter the low point in dollars		$enter the low point in dollars		$enter the low point in dollars

The above data provide three possible activity measures that could influence fuel expense. Use the high-low method to develop a cost formula for fuel expense for each of the three measures. (Round unit cost to 4 decimal places, e.g. 52.7512 and total cost to 0 decimal places, e.g. 5,275.)

Passengers:
Fuel expense	=	$enter a dollar amount passenger	+	$enter a dollar amount
Passenger miles:
Fuel expense	=	$enter a dollar amount passenger mile	+	$enter a dollar amount
Train Miles:
Fuel expense	=	$enter a dollar amount train miles	+	$enter a dollar amount
