[Question]: The population of Port Perry is seven times as many as the population of Wellington. The population of Port Perry is 800 more than the population of Lazy Harbor. If Wellington has a population of 900, how many people live in Port Perry and Lazy Harbor combined?
[Answer]: Population of Port Perry is 900 * 7 = 6,300. Population of Lazy Harbor is 6,300 - 800 = 5,500. Combined population is 6,300 + 5,500 = 11,800.

[Question]: 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?
[Answer]: 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.
So the answer is 52.
