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:

10%

Explanation:

Use future value formula

Future Value = Present Value ((1+r)^n)

26,600 = 20,000 ((1+r)^3

26,600/20,000 = (1+r)^3

1.33 = (1+r)^3

1.33^1/3 = 1+r

1.0997 = 1+r

1.0997 - 1 = r

r = 0.997 = 9.97% = 10% (rounded of to the nearest whole percentage)
