   C. Rosie knows that she paid a total of $30 for the yoga classes. She doesn't know how many classes she's gone to so far.
   D. Rosie knows that she paid a total of $30 for the yoga classes. She does not know how many classes she bought.

Answer 1

30/m would best describe situation D. Rosie has paid $30. Dividing it by m would mean she wants to know how many she can get out of that $30, which would imply she doesn't know how many classes she's bought.
