Rachel earned $200 babysitting. She spent 1/4 of the money on lunch. She spent 1/2 of the money on a DVD. How much did Rachel have left? Let's answer step by step:
Rachel spent 1 / 4 * 200 = $50 on lunch. Rachel spent 1 / 2 * 200 = $100 on a DVD. Rachel has 200 - 50 - 100 = $50 left. The answer: 50.
