Mandy is an engineer at an oxygen tank supply company. She conducted an experiment to find possible tank sizes. The maximum pressure in the tank cannot be more than 3000 psi. To model the oxygen tank, she trapped a 5-hour supply of oxygen gas inside a container fitted with a plunger. As she pressed down on the plunger, the volume of the chamber decreased. Mandy measured the pressure inside the container with a pressure gauge and recorded her data in a table.
