Judith took a total of 20 quizzes over the course of 5 weeks. After attending 10 weeks of school this quarter, how many quizzes will Judith have taken in total? Solve using unit rates.

To solve this problem using unit rates, we can determine how many quizzes Judith takes per week, and then use that rate to find out how many quizzes she'll have taken after 10 weeks.

### Step 1: Find the unit rate of quizzes per week
Judith took 20 quizzes over the course of 5 weeks. To find how many quizzes she takes per week, divide the total number of quizzes by the number of weeks:

\[
\text{Quizzes per week} = \frac{20 \text{ quizzes}}{5 \text{ weeks}} = 4 \text{ quizzes per week}
\]

### Step 2: Calculate the total number of quizzes after 10 weeks
Now that we know she takes 4 quizzes per week, we can find how many quizzes she will have taken after 10 weeks by multiplying the unit rate by the total number of weeks:

\[
\text{Total quizzes after 10 weeks} = 4 \text{ quizzes/week} \times 10 \text{ weeks} = 40 \text{ quizzes}
\]

Thus, after attending 10 weeks of school, Judith will have taken **40 quizzes** in total.
