Answer:20
Explanation:
To estimate the number of buses Jamie needs, he can divide the total number of people going to the picnic by the number of people each bus can carry:
1,344 ÷ 56 ≈ 24 buses.
To check if using compatible numbers makes sense, Jamie can use 60 and 1,200, which are both multiples of 10 and closer to the actual numbers:
1,200 ÷ 60 = 20 buses.
Since 20 buses is less than the estimated 24 buses, Jamie will not have enough buses to transport all the people to the picnic. He may need to rent or borrow additional buses or find alternative transportation solutions.
