Final answer:
To find the number of students who feel more focused after exercising, 80% of the 950 surveyed students is calculated, resulting in 760 students.
Step-by-step explanation:
The student is asking how to calculate the number of students who say they feel more focused after exercising, based on a percentage from a survey. If 80% of 950 students feel more focused after exercising, the calculation to find out how many students that represents is as follows:
Number of focused students = 80% of 950
Number of focused students = 0.80 × 950
Number of focused students = 760
Therefore, 760 students out of the 950 surveyed said they feel more focused after exercising.
