My sister loves to go shopping. Yesterday she borrowed a wad of money from Mom and went to the mall. She began her excursion by spending $18 on a new music compact disc. Then she spent half of her spending money on a new dress. Then she spent $11 taking herself and her on a book. On her way home she bought gas for $12 and spent one-fourth of her remaining money on a discount tape at the convenience store. Finally, she slipped me $2 when she got home and gave Mom back $10 in change. Mom was furious and demanded an explanation of where the money went. What did Sis tell her? (List the items and the amount spent on each item.)
