In the course of routine checking of all journal entries prior to preparing year-end reports, Betty Eller discovered several strange entries. She recalled that the president’s son Joe had come in to help out during an especially busy time and that he had recorded some journal entries. She was relieved that there were only a few of his entries, and even more relieved that he had included rather lengthy explanations. The entries Joe made were: (1) Work in Process Inventory 25,000

Cash 25,000

(2) Manufacturing Overhead 12,000

Cash 12,000

(3) Wages Expense 120,000

Cash 120,000

(4) Work in Process Inventory 3,000

Raw Materials Inventory 3,000

(a) How should Joe have recorded each of the four events?

(b) If the entry was not corrected, which financial statements (income statement or balance sheet) would be affected? What balances would be overstated or understated?
