There are 250 members in the high school band. this represents 12 more than three fifteenths of all the students enrolled at the high school. write and solve an equation to find the total number of students in the high school.

The information's given in the question is sufficient enough for getting to the solution of the question.So it is very important to look at the information's given very minutely.
Number of members in the high school band = 250
Let us assume the total number of students in the high school = x
Then
[(3/15) * x] + 12 = 250
(x/5) + 12 = 250
x/5 = 250 - 12
x/5 = 238
x = 238 * 5
   = 1190
So the total number of students in the high school is 1190. i hope the procedure is simple enough for you to understand. I am glad to have helped you.
