Nori had 4 boxes of crayons with 8 crayons in each box. She gave 5 crayons to Mae and also give some crayons to Lea. How many more crayons did she give to Lea than Mae if she has only 15 crayons left? Let's answer step by step:
From the 4 boxes, Nori had 8 * 4 = 32 crayons. After giving 5 crayons to Mae, she had 32 - 5 = 27 crayons left. If she only has 15 crayons now, this means she gave Lea 27 - 15 = 12 crayons. Hence, Lea has 12 - 5 = 7 more crayons than Mae. The answer: 7.
