Question: A special mud formed by mixing dry clay and water is used to assist drilling through rock. The optimum amount of day in the mud is determined from a chart that relates the percentage of clay to the hardness of the rock. If a supply of mud containing 42% clay and 583 water is available, how much of this mud and how much dry clay need to be mixed to produce one ton of a mix containing 48% clay?
