b = shoe price
s = sock price
2 b + 4 s = 125 times 3
3 b + 5 s = 182 times 2
6 b + 12 s = 375
6 b + 10 s = 364
----------------- subtract
2 s = 11
s = $5.50
s = sock price
2 b + 4 s = 125 times 3
3 b + 5 s = 182 times 2
6 b + 12 s = 375
6 b + 10 s = 364
----------------- subtract
2 s = 11
s = $5.50
