How did M Loisel contribute to the cost of the new necklace?

Mme. Loisel was forced to forfeit everything of their joy and ease in order to pay back the necklace's purchase price. She and her husband relocated and rented an attic inside a building. She let their servant go in an effort to save costs in any way she could. Without regard for her beauty or charm, Mathilde was forced to handle all the household duties by herself. Every day, she fetched water, washed the dirty clothes, and scrubbed the greasy dishes. She went to the market and haggled with several people to get the best deal possible.
