Agrain silo at a train-car loading station contains 9,450 cubic feet of grain before loading begins. The grain is loaded from the silo into train cars at the rate of 21 cubic feet per minute.
Which equation can be used to find the volume, V. of grain in the silo t hours after loading begins?
O V = + - 9,450
O V = (21) (60) - 9,450
O V = 9,450 -
O V = 9,450 - (21) (60)
