Answer:
177 ft below sea level
Step-by-step explanation:
282
10 x 12 = 120. This represents how man ft the hot air balloon rose.
282 - 120 = 162. Keep in mind your still below sea level.
162 + 15 = 177
You add 15 because the hot air balloon is going down 15 feet which adds to being below sea level. ( Your going deeper/lower)
