Question: Carly practices her butterfly stroke for 3 hours a day, 4 days a week, and her backstroke for 2 hours a day, six days a week. How much time does she spend practicing swimming in a month with 4 weeks? Think carefully first, then make a decision:
First find the total time Carly practices the butterfly stroke in a week: 3 hours / day * 4 days / week = 12 hours / week. Then find the total time Carly practices the backstroke stroke in a week: 2 hours / day * 6 days / week = 12 hours / week. Then add those two amounts of time to find her total practice time each week: 12 hours / week + 12 hours / week = 24 hours / week. Then multiply her weekly practice time by the number of weeks in a month to find her monthly practice time: 24 hours / week * 4 weeks / month = 96 hours / month. So the answer is 96.
