Pls help.

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

3D = 4C
15D = 20C

5D + 6C -> 76
15D + 18C -> 228

20C + 18C -> 228
38C -> 228
1C -> $6
