Solve each problem.Momma's ice cream shop sells three types of ice cream: soft-serve, chunky, and nonfat. Location I sells 10 gal of soft-serve, 100 gal of chunky, and 30 gal of nonfat ice cream each day. Location II sells 14 gal of soft-serve and Location III sells 60 gal of soft-serve each day. Daily sales of chunky ice cream are 90 gal at Location II and 120 gal at Location III. At Location II, 17 gal of nonfat are sold each day, and 40 gal of nonfat are sold each day at Location III.
