Give the step-by-step reasoning process and then the final answer. Hans reserved a table at a fine dining restaurant for twelve people. 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. Two of the people in Hans's party are his kid cousins, and the rest are adults. How many dollars does Hans have to pay as a deposit for the restaurant reservation?
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.
The final answer: 52.
