Question: When all her clothes are washed and in her closet, Brie has 12 blouses, 6 skirts, and 8 slacks. Today in her hamper, she has 75% of her blouses, 50% of her skirts, and 25% of her slacks. How many pieces of clothing will she need to put in the washer?
Answer with step-by-step thinking: In her hamper, Brie has 12 x 75% = 9 blouses. In her hamper, she has 6 x 50% = 3 skirts. In the hamper, she has 8 x 25% = 2 slacks. She will need to wash 9 + 3 + 2 = 14 pieces of clothes.
So the answer is 14.

Question: Maddy was given 40 chocolate eggs for Easter. She likes to eat two each day after school. If Maddy has two chocolate eggs after school each day, how many weeks will they last?
Answer with step-by-step thinking:
Maddy is eating 2 eggs each day after school and there are 5 school days in a week, so she eats 2 x 5 = 10 eggs each week. Since Maddy has 40 eggs / 10 eggs each week, they will last 4 weeks.
So the answer is 4.
