Part A A hot air balloon is at an altitude of 100 yards. The balloon's altitude decreases by 10 yards every minute
Which equation can be used to determine the number of minutes m it will take the balloon to reach an altitude of 60 yards?
OA) 10 + 100m = 60
OB) 10 - 100m = 60
I
O C) 100+ 10m = 60
OD) 100 - 10m = 60
