To find out how many quizzes Keenan will have taken in total after attending 5 weeks of school, we first need to determine the rate of quizzes taken per week based on the information given.
Keenan took 12 quizzes over the course of 3 weeks. To find the rate of quizzes taken per week, we can calculate:
\[ \text{Quizzes per week} = \frac{\text{Total quizzes}}{\text{Total weeks}} = \frac{12 \text{ quizzes}}{3 \text{ weeks}} = 4 \text{ quizzes per week} \]
Now that we know Keenan takes 4 quizzes each week, we can calculate the total number of quizzes taken over 5 weeks:
\[ \text{Total quizzes in 5 weeks} = \text{Quizzes per week} \times \text{Number of weeks} = 4 \text{ quizzes/week} \times 5 \text{ weeks} = 20 \text{ quizzes} \]
So, after attending 5 weeks of school, Keenan will have taken a total of 20 quizzes.
