If the crew members used 3 gal of paint per hour and bought 30 gal of paint for a job, then they will work 30:3=10 hours.

  1. They start at x=0 hours with y=30 gal of paint;
  2. They end at x=10 hours with y=0 gal of paint (they worked until they used all the paint).
  3. The dependence between x and y is linear.

Conclusion: the only possible sketch is A.

Answer: correct choice is A.
