Final answer:

Pamela will need to attend school for 3 weeks to take a total of 30 quizzes.

Step-by-step explanation:

To find out how many weeks of school Pamela will have to attend to take a total of 30 quizzes, we can set up a proportion using the relationship we know: 20 quizzes in 2 weeks.

Let x represent the number of weeks Pamela needs to attend school for 30 quizzes.

Using the proportion: 20 quizzes / 2 weeks = 30 quizzes / x weeks

Now we can cross-multiply: 20x = 2 * 30.

Simplifying, we have 20x = 60.

Dividing both sides by 20, we find that x = 3.

Therefore, Pamela will need to attend school for 3 weeks in order to take a total of 30 quizzes.
