The equation for profit is expected to be
  daily profit = (profit on plate)*(number of plates) +(profit on cup)*(number of cups)

We are told that
  profit on plate = k
  profit on cup = k-1
Matching these to the expression above, we find
  x = number of plates
  y = number of cups

You are asked what y represents. It is
  A. The number of cups sold in one day.
