My question is: Rex is taking lessons for his driver’s license. He wants to take 40 hour-long lessons before his test, and decides to have two-hour sessions twice a week until he has done his test. After 6 weeks, how many more weeks will Rex need to continue taking lessons to reach his goal? Your thoughts:
Each week, Rex is taking 2 hour - long lessons * 2 times a week = 4 lessons. After 6 weeks, he has done 4 lessons per week * 6 weeks = 24 lessons. So Rex still needs 40 total lessons – 24 lessons taken = 16 lessons. He will therefore need lessons for another 16 lessons / 4 lessons per week = 4 weeks. The final answer: 4.
