Lee took a total of 35 quizzes over the course of 5 weeks. After attending 9 weeks of school this quarter, how many quizzes will Lee have taken in total? Assume the relationship is directly proportional.

quizzes

Since Lee took 35 quizzes over 5 weeks, we can find the rate at which Lee takes quizzes by dividing the number of quizzes by the number of weeks. So the rate is 35 quizzes / 5 weeks = <<35/5=7>>7 quizzes per week.

If the relationship is directly proportional, then the number of quizzes Lee will take in 9 weeks is 7 quizzes/week * 9 weeks = <<7*9=63>>63 quizzes. Answer: \boxed{63}.
