An airplane is flying at an altitude of 8500 metres. It begins descending at a rate of 250 metres per minute for 6 minutes. The pilot then ascends another 125 metres per minute for 4 minutes. Finally, the airplane descends another 300 metres. What is the airplanes final altitude?
1) -250 x 6 = -1500
2) 125 x 4 = 500
3) 8500 + (-1500) + 500 - 300 = 7200m
