Eggs for Sale
Down the line, another employee puts the eggs into either of two hoppers, each egg according to its stamp. The system works reasonably well, all things considered, except that Old Fred has a heavy hand and on the average breaks 30% of the 120 eggs that pass by him each minute. At the same time, a check of the “X-large” stream reveals a flow rate of 70 eggs/min, of which 25 eggs/min are broken.
QUESTION: 1.) How many “large” eggs leave the plant each minute? 2.) Is Old Fred right- or left-handed?
