conversations.value: For 5 apples, Mary will pay 5*1= 5 dollars.
  For 3 oranges, she will pay 3*2= 6 dollars.
  For 2 bananas, she will pay 2*3 = 6 dollars.
  She bought 5+3+2=10 fruits
  For 10 fruits, Mary gets a discount of 10/5 = 2 dollars.
  In total, the bill is 5 + 6 + 6 = 17 dollars.
  Subtracting the discount offered by the stores, Mary will pay 17 - 2 = 15 dollars.
