Answer:
Janet has attended 4 weeks of school this quarter, so she will have taken a total of 20.
Step-by-step explanation:
1. Start with the given information: Janet took 10 quizzes over the course of 2 weeks.
2. Calculate the rate of taking quizzes: 10 quizzes / 2 weeks = 5 quizzes per week.
3. Determine the number of quizzes Janet will have taken after 4 weeks by multiplying the rate by the number of weeks: 5 quizzes/week * 4 weeks = 20 quizzes.
4. Therefore, Janet will have taken a total of 20 quizzes after attending school for 4 weeks.
