She uses \$500 to buy a necklace for her daughter at Tiffany's. Tiffany's pays Stelios \$950 per week to appraise jewelry. Stelios uses \$10 to purchase breakfast from Dinah's Diner.

"1RJ Ginny earns \$300 per week working for Dinah's Diner. "0 Ginny spends \$500 to buy a necklace for her daughter.
