A = dog food, b = cat food
1a + 2b= 25
2a + 1b = 26
simultaneous equations!!
2a + 4b=50
2a + 1b = 26
subtract from each other
2a - 2a = 0
4b - 1b = 3b
50 - 26 = 24
3b = 24
b = $8
then sub into equation
1a + 2(8) = 25
25-16 = 9
a= $9
The answer is 105 students.
It would be a right scalene triangle.
hope this helped :)
