Regression Analysis. The city of Rockville reported the following annual cost data for maintenance work performed on its fleet of trucks.
	Reporting Period (Year)	Total Costs	Level of Activity (Miles Driven)
	Year 1	750,000	225,000
	Year 2	850,000	240,000
	Year 3	1,100,000	430,000
	Year 4	1,150,000	454,000
	Year 5	1,250,000	560,000
	Year 6	1,550,000	710,000
Required:
1. Use the regression slope / intercept formulas to develop the cost equation Y = f + vX. [Hint: Watch the video lecture on "mixed cost calculations" before you attempt this problem.]

	Slope
	Intercept
	Y =	f +	v *	X
	Y			X
	** Solve for Y
2. What would the city of Rockvilles estimated costs be if its trucks drove 500,000 miles in year 7?
	Y =	f +	v *	X
