conversations.value: Find a solution for this math problem: Liezl prepared four sets of 2-dozen paper cups for her daughter's birthday party. If 5 cups were damaged and 30 were not used, how many paper cups were used?

conversations.value: Since 1 dozen is equal to 12 then 2 dozens of cups is equal to 2 x 12 = 24 cups.
  So, Liezl prepared a total of 24 cups x 4 sets = 96 paper cups.
  A total of 5 + 30 = 35 paper cups were not used.
  Hence, 96 - 35 = 61 paper cups were used.
