Answer:

Troy should have 28 pounds left in the cylinder.

Step-by-step explanation:

So here's what we're given:

Amount of gas in cylinder = 50 pounds

Amount of gas used in Ms. Jones system = 13 pounds

Amount of gas used in client system = 9 pounds

Here's what we need to find:

Amount of gas still in cylinder

Now here's what we need to compute:

Amount of gas still in cylinder = Amount of gas in cylinder - Amount of gas used in Ms. Jones system - Amount of gas used in client system

Amount of gas still in cylinder = 50 - 13 - 9

Amount of gas still in cylinder = 28 pounds

Hope I helped! ☺
