You can put this solution on YOUR website!
let x be the number of Snack A
let (6-x) be the number of Snack B (since we know teacher bought 6 snacks, x of them are Snack A, then the numbers left 6-x must be for snack B)

4.75x + 6.25(6-x) = 34.50
4.75x + 37.5 - 6.25x = 34.50
-1.5x = -3
1.5x = 3
x = 2
Snack A = x = 2
Snack B = 6-x = 6-2 = 4
Therefore the teacher bought 2 snack A and 4 snack B
