Question

Rosie wrote this expression to describe the amount she paid for each yoga class. 30 / m Which situation could be described by this expression?
   A. Rosie knows that each yoga class costs $30. She doesn't know how many classes she bought.
   B. Rosie knows that she paid $30 for one yoga class. She does not know the total amount she spent.
   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.
