1 A gross refers to a group of 144 items (a dozen dozen or a square dozen).  A great gross refers to a group of 1728 items (a dozen gross or a cubic dozen).
Note that the gross profit is the percentage of the adjusted revenue to cover taxes and a net profit of 9%. Tax is 23% of gross. Therefore gross = (.23g + .09); therefore .77g = .09; then g=.09/.77 = .1169 or Gross Profit (sometimes referred to as Ordinary Income) = 11.69% of adjusted revenue.
