Sandy sells seashells by the seashore. Lucy also sells seashells by the seashore, but her tongue-twister isn't so twisty. After one week of seashell selling, Lucy has 32 seashells left of her original 74, and Sandy has 34 left of her original 90. After how many days of seashell selling do Lucy and Sandy have the same number of seashells left?
