Cole took a total of 36 quizzes over the course of 4 weeks. How many weeks of school will Cole have to attend this quarter before he will have taken a total of 45 quizzes? Assume the relationship is directly proportional.
Step-by-step explanation: 36 / 4 = 9. This means in 1 week he finishes 9 quizzes. 9 x 5 = 45, therefore it would take him 5 weeks to finish 45 quizzes.
