Question

Terrence took a total of 63 quizzes over the course of 7 weeks. After attending 10 weeks of school this quarter, how many quizzes will Terrence have taken in total? Solve using unit rates.

Answer 1

90 quizzes

Explanation:

In 7 weeks, 63 quizzes

In 10 weeks, x quizzes

Making a proportion,

7/10 = 63/x

Cross multiplying,

7x = 630

Dividing by 7 on both sides,

x = 90 quizzes
