To solve this problem, simply use one variable to represent the number of students in each of the 2 classes.
1st class - X = no of students
2nd class - X + 6 no of students
Both classes : X + X + 6 = 50
2X + 6 = 50
2X = 44
X = 22.
1st class - X = 22 students
2nd class - X + 6 = 22 + 6 = 28 students.
There are 28 students in the larger class.
Set it into proportions.
$0.40/0.25 miles = x/15 miles
And then solve the proportion.
0.25*x = 0.40*15
0.25x = 6
0.25x/0.25 = 6/0.25
x=24
Therefore, Emily's mother donates $24 if she bikes 15 miles.
