A bucket that weighs 4.2 pounds and a rope of negligible weight are used to draw water from a well that is 84 feet deep. The bucket is filled with 45 pounds of water and is pulled up at a rate of 1.9 feet per second, but water leaks out of a hole in the bucket at a rate of 0.1 pounds per second. Find the work done pulling the bucket to the top of the well. Your answer must include the correct units.
