Answer:
[tex]3875[/tex] [tex]feet[/tex]
Step-by-step explanation:
We first start at 7,000 feet above sea level, we then descend 4,500 feet closer to the sea level, therefore:
[tex]7,000 - 4,500[/tex]
[tex]==> 2,500[/tex]
Then we go up 1,375 feet farther from the sea level, so:
[tex]2,500 + 1,375[/tex]
[tex]==> 3,875[/tex]
