I am really interested in the WORK. Explain it like you would to a little kid. I have the correct answers just trying to learn how to solve/approach (especially part B). Thanks!

Following is a diagram of the shirt-cleaning process used by the Floods of Suds One-Day Laundry Services, Inc. The shirts are soaked in an agitated tub containing Whizzo, the Wonder Detergent, and are then wrung out and sent to a rinse stage. The dirty Whizzo is sent to a filter in which most of the dirt is removed, and the cleaned detergent is recycled back to join a stream of pure Whizzo, with the combined stream serving as the feed to the washtub. Data: 1. Each 100.0lb of dirty shirts contains 2.00lb of dirt. 2. The washing removes 85.0% of the dirt in the dirty shirts. 3. For each 100.0lbm of dirty shirts, 28.0lb of Whizzo leaves with the clean shirts, of which 22.0lb is wrung back into the tub. 4. The detergent that enters the tub contains 97.0% Whizzo, and that which enters the filter contains 75.0%. The wet dirt that leaves the filter contains 8.00% Whizzo. Questions: a. How much pure Whizzo must be supplied per 100.0lb of dirty shirts? Ibm b. What is the composition of the recycled Whizzo stream from the filter? \% Whizzo
