He has to pay a deposit for the reservation, and the deposit is a flat $20 plus an extra $3 per adult but only $1 per child.

conversations.value: Hans’s party includes 12 - 2 = 10 adults and 2 children.
  The adults will cost 3 * 10 = $30 for the deposit.
  The children will cost 2 * 1 = $2 for the deposit.
  Thus, Hans has to pay 30 + 2 + 20 = $52 as a deposit for the restaurant reservation.
