Annie spends 2 hours a week on chess club, 8 hours a week on drama club, and 3 hours a week on glee club. If there are 12 weeks in each semester and Annie takes the first two weeks off sick, how many hours of extracurriculars does she do before midterms? Let's answer step by step:
First find the total number of extracurricular hours Annie does per week: 2 hours / week + 8 hours / week + 3 hours / week = 13 hours / week. Then find the number of weeks in a semester before midterms by dividing the total number of weeks by 2: 12 weeks / semester / 2 = 6 weeks / semester. Then find the number of weeks before midterms that Annie wasn't sick: 6 weeks - 2 weeks = 4 weeks. Then multiply Annie's weekly commitment by the number of weeks to find her total number of extracurricular hours: 13 hours / week * 4 weeks = 52 hours. The answer: 52.
