EXPLANATION
If Bridget took a total of 16 quizzes over the course of 4 weeks, after attending 5 weeks this quarter, we can calculate the total number of quizzes by applying the unitary method as shown as follows:
[tex]\text{Number of quizzes= }\frac{16\text{ quizzes}}{4\text{ we}eks}\cdot5\text{ w}eeks[/tex]Multiplying terms:
[tex]\text{Number of quizzes = }\frac{80}{4}=20[/tex]Answer: She took a total of 20 quizzes.
