Which number satisfies the inequality 9h + 15 > 55?

When you say "Which number ...", I expect to see a list of choices at the
end of the question, and I get very upset when there's nothing there.

                                            9h + 15 > 55

Subtract  15  from each side:          9h > 40

Divide each side by  9 :                    h > 40/9

Any number greater than (4 and 4/9) satisfies the inequality.

9h + 15 > 55
      - 15 - 15
         9h > 40
          9      9
           h > 4⁴/₉

The solution set is equal to (4⁴/₉, ∞).
