Answer 1

The initial altitude of the plane is 36,000 feet.

1. The pilot ascends the plane by 4,000 feet:
\[
36,000 + 4,000 = 40,000 \text{ feet}
\]

2. Then, the pilot lowers the plane by 5,500 feet:
\[
40,000 - 5,500 = 34,500 \text{ feet}
\]

So, the new altitude of the plane is **34,500 feet**.
