2m + 4s = 66.
4m + 3s = 84.
(Double the 2 glass of milk and 4 snack bars)
4m + 8s = 132.
4m + 3s = 84.
(Take away the second equation from the first equation)
5s= 48.
s = 48/5.
s = 9.6.
4m + 3(9.6) = 84.
4m + 28.8 = 84.
4m = 84 - 28.8.
4m = 55.2.
4m/4 = 55.2/4.
m = 13.8.
In a glass of milk, there are 13.8 carbs, and in a snack bar, there are 9.6 carbs.
2(13.8) + 4(9.6) = 66.
