776-232.8= 543.2
Answer:
The answer is 3
Step-by-step explanation:
Number of students taking Spanish class this year in Brooke's school = 60
Percentage increase in the number of students
taking Spanish class from last year = 25%
Then
Number of students that are taking Spanish
class more than last year = 25/100 * 60
= 15
Then
The number of students that took Spanish class last year = 60 - 15
= 45 students
So the number of students that took Spanish class last year was 45. I hope the answer is clear to you and the procedure is also easy for you to understand.
