Solve the problem.A ball is dropped from a height of 25 feet. Each time it strikes the ground, it bounces up to 0.7 of the previous height. The total distance the ball has travelled before the second bounce is 
feet, and the total distance the ball has travelled before bounce n + 1 is 25 + 
feet.Use facts about infinite geometric series to calculate the total distance the ball has travelled by the time it has stopped bouncing.
