Month		Cost		No. of Tickets Sold
January		$160,000		19,000
February		190,000		22,000
March		215,000		28,000
April		217,000		29,000
May		209,500		29,500
June		194,500		24,500
July		240,000		35,000
August		172,000		20,000
September		185,000		22,000
October		202,000		26,000
November		191,500		23,500
December		207,000		30,000

Use the high-low method to estimate fixed cost per month and variable costs per ticket sold [i.e., estimate a and b in the equation Cost = a + (b # of tickets) using the high-low method]. (Round variable cost per ticket to 2 decimal places, e.g. 15.25 and other answer to 0 decimal places, e.g. 125.)

Cost = $____ + $____ x # of tickets sold
