At an electronics store, the number of 37-inch HGTVs that is expected to be sold in a month is double that of 58-inch HGTVs and 50-inch HGTVs combined.
Sales of 58-inch and 50-inch HGTVs are expected to be equal.
58-inch HD-TVs sell for $4800
50-inch HD-TVs sell for $2000
37-inch HGTVs sell for $1800
If total sales of $168,000 are expected this month, how many of each HDTV should be stocked?
