Problem: The newly launched Vortex Company manufactures car batteries that it sells through retailers such as AutoZone. It has entered the market sequentially, beginning with the Midwest. After six months from launch, its sales across the area are split as follows: 18% Indiana, 22% Illinois, 10% Kansas, 12% Michigan, 27% Ohio, and 11% Wisconsin. The industry's relative sales in those same areas are as follows: 16% Indiana, 18% Illinois, 9% Kansas, 30% Michigan, 20% Ohio, and 7% Wisconsin. Calculate Vortex's BDI across its markets.
