Since the relationship is directly proportional, we can set up a proportion to solve for the number of weeks Aubrey needs to attend school:
16 quizzes / 4 weeks = 20 quizzes / x weeks
Cross multiplying, we get:
16 * x = 4 * 20
16x = 80
Dividing both sides by 16, we find:
x = 80 / 16
x = 5
Therefore, Aubrey will have to attend school for 5 weeks before she will have taken a total of 20 quizzes.
or
Aubrey took a total of 16 quizzes over the course of 4 weeks. How many weeks of school will Aubrey have to attend this quarter before she will have taken a total of 20 quizzes? Assume the relationship is directly proportional.
