Answer 1

	Month	Jerseys Printed(X)	Total Cost(Y)(in $)	Square of X	X*Y(in $)
	Jan	215	5,835	46,225	12,54,525
	Feb	195	5,685	38,025	11,08,575
	Mar	230	5,930	52,900	13,63,900
	Apr	550	8,575	3,02,500	47,16,250
	May	675	9,770	4,55,625	65,94,750
	Jun	655	9,260	4,29,025	60,65,300
	Jul	455	6,230	2,07,025	28,34,650
	Aug	375	6,175	1,40,625	23,15,625
	Sep	310	6,005	96,100	18,61,550
	Oct	230	5,960	52,900	13,70,800
	Nov	185	4,960	34,225	9,17,600
	Dec	175	4,800	30,625	8,40,000
	Total	4,250	79,185	18,85,800	3,12,43,525
		Unit Variable Cost (b) = nΣxy − (Σx)(Σy) /nΣx^2 − (Σx)^2		Total Fixed Cost (a) = Σy − bΣx / n
	So here n =12 ,Σx =4,250, Σy =79,185, Σx^2=18,85,800 ,Σxy =33,12,43,525
	Variable cost per unit(b) =12*3,12,43,525 - (4,250*79,185) / 12*18,85,800 - 4,250^2
	Variable cost per unit(b) =37,49,22,300 - 33,65,36,250 / 2,26,29,600 - 1,80,62,500
	Variable cost per unit(b) =3,83,86,050 / 45,67,100 =$8.40
	Total Fixed cost =79,185 - ($8.40*4,250) / 12
	Total Fixed cost =(79,185 - 35,700) / 12
	Total Fixed cost =$43,485 / 12 =$3,623.75
	Y =$3,263.75 + $8.40X
	At 640 jerseys, Total Costs =$3,263.75+$8.40*640 =$8,639.75 or $8,640
