1, first divided by the largest number (the number of large ships) mainly depends on the remainder. Suppose a * * 32 people, a boat 24 yuan and a ship 30 yuan: 32÷6 equals 5 (bars) ... two (people).

2. As mentioned above, that is five big ships and one small boat: 30×5+24 times 174 yuan. Vacant seats will save money: two people in a small boat and six people in a big boat can also save money by arranging them into two small boats: four big boats: 30×4 equals 120 yuan, and two small boats: 24×2 equals 120+48 equals 160 yuan in 48 yuan.
