The Armer Company is accumulating data to be used in preparing its annual profit plan for the coming year. The cost behavior pattern of the maintenance costs must be determined. The accounting staff has suggested that linear regression be employed to derive an equation in the form of y = a + bx for maintenance costs. Data regarding the maintenance hours and costs for last year and the results of the regression analysis are as follows:

	Hours of Activity		Maintenance Costs
January	470		$ 4,400
February	300		2,800
March	430		3,300
April	270		2,860
May	500		4,400
June	300		2,910
July	310		3,070
August	530		4,700
September	500		4,270
October	460		3,970
November	330		3,500
December	330		3,280
Sum	4,730		43,460
Average	394		3,622

Using the high-low method to estimate cost behavior, 400 maintenance hours in a month would mean the maintenance costs would be budgeted at: (Round your intermediate calculations and final answer to 2 decimal places.)
