No. You must be getting tired.
To find out how many students will wear school colors at the next pep rally, you need to use the information given: 3 out of 7 students wore colors at the previous pep rally.
First, you need to find the ratio of students who wore colors to the total number of students at the previous pep rally. To do this, divide the number of students who wore colors by the total number of students:
Ratio = Number of students who wore colors / Total number of students
Ratio = 3 / 7
Next, you can use this ratio to estimate the number of students who will wear school colors at the next pep rally. Multiply the ratio by the total number of students at the next pep rally:
Number of students wearing colors = Ratio * Total number of students at the next pep rally
Number of students wearing colors = (3 / 7) * 350
Now, calculate the answer:
Number of students wearing colors = (3 / 7) * 350 = 150
Therefore, the answer is A. 150 students will wear school colors at the next pep rally.
