a supply chain is adding value to a product. (think of cotton starting in a field, being turned into cotton thread, then a shirt, then a designer shirt.) at the point of extraction the value added to the product is $10. at the point of manufacture the value added to the product is an additional $12. at the point of the wholesaler the value added is an additional $14. then finally at the point of retail sale the value added is an additional $16. (part a) in the european union this product would be subject to a 15% value added tax. how much tax will be due at each stage of the products development? (i.e.: extraction, manufacture, wholesale, and retail.) (part b) in chicago, il this product would be subject to a 6.25% illinois state sales tax and a 10.25% chicago city sales tax. how much tax will be due at each stage of the products development? (again: extraction, manufacture, wholesale, and retail.)
