A gardening company sells clay flower pots and plastic flower pots. There must be at least 2 pots in each shipment, but there cannot be more than 8 in a shipment.
Additionally, the shipment must weigh less than 100 pounds. Each shipment container
weighs 20 pounds, and there is 1 pound of packing material. A clay flower pot weighs
15 pounds, whereas a plastic flower pot weighs 7.5 pounds.
Write a system of inequalities that represents the constraints on the number of pots
that can be included in one shipment.
