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.
Answer
5 days and six hours or 126 hours
If X is the weight of the package in pounds:
1.24x + 2.49 = 11.17
1.24x = 8.68
x = 7
The package weighs exactly 7 pounds.
