The graph gives a breakdown of the hours students use the tutoring center. If the graph is based on 300 students, how many used the center 8 to 10 hours during the week?

1-3 h 27%
3-5 h 22%
5-8 h 26%
8-10 h 15%
over 10 h 10%

0.15 * 300 = ?

10 To find out how many students used the tutoring center for 8 to 10 hours during the week, you need to calculate 15% of the total number of students.

Step 1: Calculate the number of students represented by 1% of the total.
- Divide the total number of students, 300, by 100 to get 1%: 300 / 100 = 3.

Step 2: Calculate the number of students represented by 15%.
- Multiply the number of students for 1% by 15: 3 x 15 = 45.

Therefore, 45 students used the tutoring center for 8 to 10 hours during the week.
