conversations.value: On Monday a group of 7 children and 5 adults went to the zoo. On Tuesday a group of 4 children and 2 adults went as well. Child tickets cost $3, and adult tickets cost $4. How much money did the zoo make in total for both days?
  How to solve this?

conversations.value: The total amount of children that went on both days is 7 + 4 = 11.
  The cost of the children's tickets is 11 × $3 = $33.
  The total amount of adults that went on both days is 5 + 2 = 7.
  The cost of the adults' tickets is 7 × $4 = $28.
  The zoo made $33 + $28 = $61 in total.
