Weeks = ?

Answer 1

Ayana will need to attend 1 more week of school to reach a total of 15 quizzes, calculated using a unit rate of 5 quizzes per week.

Step-by-step explanation:

Ayana took a total of 10 quizzes over the course of 2 weeks, which establishes a unit rate of 5 quizzes per week (10 quizzes / 2 weeks). To find out how many additional weeks Ayana needs to attend school to take a total of 15 quizzes, we can calculate as follows:

1. First, determine the total quizzes already taken: 10 quizzes.
2. Subtract the total quizzes taken from the desired total: 15 quizzes - 10 quizzes = 5 quizzes remaining.
3. Using the unit rate of 5 quizzes per week, divide the remaining quizzes by the unit rate: 5 quizzes remaining / 5 quizzes per week = 1 week.

Therefore, Ayana will have to attend school for 1 more week to reach a total of 15 quizzes.
