Answer:
10 Students.......Yo Jake,found out the answer by myself.......here you go :)
Explanation:
x = total students
No. of students by Walk=7
No of students by Ride=2/5
No. of student by Parents=32%
Therefore........ x - 2/5 * x - 32/100 * x= 7
= 25 {Value of X}
Now you just apply it.... 2/5 of x
=2/5 of 25
= 10 Students
