There are 4 planes which are in line to take off. The first plane has 147 passengers, the second has 123 passengers, the third has 101 passengers, and
the fourth has 53 passengers. Which of the following is a good estimation of how
many passengers are on these four planes?

424

Step-by-step explanation: add them up

The estimate would be 400 passengers.

Step-by-step explanation:

So first, you would add all those numbers together.

147 + 123 + 101 + 53 = 424

After you get your number you would round. The number i got was 424 so i would round down because if it was 50 and over i would round up, But is it was 50 and down you would round down.

So after rounding i got 400.

Hope this helps if this is how you would solve it.
