Answer:
18.1 m
Step-by-step explanation:
For this problem, we will simply use the initial height of 0 meters, the height of 25 meters after 2 minutes, the decline of 2.2 meters every minute for 7 minutes, and a final increase of 8.5 meters to find the final altitude of the ballon.
0m + 25m - 2.2m(7) + 8.5m = ?
25m - 15.4m + 8.5m = ?
9.6m + 8.5m = ?
18.1m = ?
Hence, the final altitude of the ballon is 18.1m.
