 <translate> 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. <yor> Lákọ̀ọ́kọ́ ná, wo iye wákàtí tí Annie fi ń ṣe àwọn iṣẹ́ àṣesìnlú lọ́sọ̀ọ̀sẹ̀: wákàtí méjì lọ́sẹ̀ + wákàtí mẹ́jọ lọ́sẹ̀ + wákàtí mẹ́ta lọ́sẹ̀ = wákàtí mẹ́tàlá lọ́sẹ̀.
