System of Inequalities Problem Solving Task
Wait!! I Need my Weights!

Eric runs a dive boat named the Lois Ann. He has been struggling to fill his boat and he doesn't understand why. Eric provides weights for the scuba divers that go out on the boat. He has a maximum of 220 pounds of weight available for the divers to use and estimates that the average adult needs 20 pounds of weight and the average child needs 10 pounds of weight. Eric also likes to provide his divers with tanks to use. For each trip each adults requires 2 tanks and each child requires only 1 tank. The Lois Ann can accommodate at most 30 tanks and can hold a maximum of 20 scuba divers on any trip.
