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.
