To determine which graph’s shaded region shows the possible combinations of argon gas and pure oxygen that a welder can buy, you’ll need to look for the graph that represents the constraints or limitations set by the quantities of each gas available.
Here’s how to analyze the options:
1. Identify axes: Typically, one axis would represent the quantity of argon gas, and the other would represent the quantity of pure oxygen.
2. Shaded region: The shaded area should indicate all the possible combinations that do not exceed any limits (like maximum amounts of each gas) that are set by the welder’s budget or availability.
3. Feasibility: Ensure that the shaded area is realistic and falls within the feasible limits for the amounts of argon and oxygen that can be purchased together.
Once you evaluate these aspects in the graphs labeled A, B, C, and D, you should be able to identify the correct answer based on these criteria. If you’re still unsure, feel free to reach out for further explanation or assistance!
