Final answer:
To find how many students' favorite color was blue, multiply the total number of students surveyed (600) by 15% (0.15), yielding 90 students. Therefore, the correct answer is 90 students (Option C).
Step-by-step explanation:
To calculate the number of students whose favorite color is blue according to Nolan's survey, we need to find 15% of the 600 students. To do this, we multiply the total number of students, 600, by the percentage in decimal form, which is 0.15 for 15%.
Using the formula:
- Number of students = Total students × Percentage of students
- Number of students = 600 × 0.15
- Number of students = 90
Thus, 90 students said their favorite color was blue, making option C the correct answer.
To find the number of students whose favorite color is blue, we multiply the total number of students by the percentage who said blue is their favorite color. In this case, 15% of 600 students is calculated as:
15% of 600 = 0.15 × 600 = 90
Therefore, the correct answer is 90 students (Option C).
