Question 1097807: With each stroke, a pump removes 1/4 of the air in a container. After 5 strokes, what is the fraction of the original amount of air in the container that is left? Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! If the pump removes 1/4 of the air, then it leaves 3/4 of the air in the container. With each stroke, only .75 of the original air is left. So, 0.75^5=0.2373046875, which is the fraction of air left in the container
