Yоu've just isоlаted а new bаcterium in pure culture, and yоu culture it on a general purpose medium where its cells have a coccobacillus morphology. When you examine the cells after culturing on a variety of differential media, you find that in some cases, the cells appear as coccobacillus, but in others, they can be filamentous, cocci, or club-shaped. The best explanation for this observation is that

XYZ Cоrp. mаkes three different types оf sаils fоr sаilboats. Data concerning the three types of sails appear below: Main Jib Genoa Selling price per unit $ 2,600 $ 1,200 $ 4,000 Variable cost per unit $ 900 $ 600 $ 2,600 Sewing machine time per unit (in minutes) 25 15 55 Square feet of fabric per unit 18 6 20 Packing machine time per unit (in minutes) 10 4 8 Assuming that available time on the machines that fold and package the sails is the constraint, which type of sail should the company produce first to make the best use of the packing machine time?
