There are usually 20 boats in the Binhe Park, which can accommodate 960 people for boating every day. Every holiday, the park adds 10 boats. Based on the original number of passengers per boat, how many people can be accommodated on the boat every day during holidays?

Method 1: First find out how many people each boat can accommodate for boating every day.

960 × 20 = 48 (people)

Find the total number after adding 10 ships.

20 + 10 = 30 (items)

Finally, find out how many people can take a boat trip every day during holidays.

480 + 960 = 1440 (person)

Answer: It can accommodate 1,440 people taking boat trips every day during holidays.

practice

1. First tell the order of operations of the following questions, and then calculate.

(4.8+12.5)×(8-2.4) 1200-(15+20)×32

= 17.3×5.6 = 1200-35×32

= 96.88 = 1200-1120

= 80
