During a sale, Wilson spent $120 on a pair of shoes. He spent 2/5 of the remaining money on a bag and a book. After his spending, Wilson realized that he had 1/3 of his money left. If the book cost 1/2 as much as the bag, how much is the bag.
Thanks in advance

Thanks[/quote]Sorry, can explain why the shoes is 4 units ?

[The Right Equation]

shoes are 4 units as seen from the individual ratio units formed (from Repeated-Identity Concept). Either using models or repeated-identity ratio units, shoes will always be 4 units.
