find how many carb is in one glass of milk and one snack bar?
Answer provided by our tutors
let
m = the carbs in 1 glass of milk
s = the carbs in 1 snack bar
3 glass of milk and 2 snack bar have a total of 56 carbohydrate(carbs)
3m + 2s = 56
2 glass of milk and 3 snack bar have a total of 54 carbohydrate (carb)
2m + 3s = 54
by solving the system of equations
3m + 2s = 56
2m + 3s = 54
we find
m = 12 carbs
s = 10 carbs
