43

Step-by-step explanation:

So it can carry 30 children OR 29 adults.

All the passengers were children, and it carried a full load 43 times.  So 30 children is the full load, then 30x43 is 1290.

It carried 1290 children.

If all the passengers were adults, then we can do 29x43=1247.

1290-1247 is 43.

In fact, in 30x43 and 29x43, 30-29 is actually just one! So one times forty three is 43.

Here's ur answer

I think 43 Because if it was all adults it would be less people, but since it was children it would be 1 more person each time. Since it went 43 times 43 more people than if it was adults If that’s what it’s asking…
