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

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.
