Determine how many carbs are in one glass of milk and in one snack bar.

Question

two glasses of milk and 3 snack bars have a total of 73 carbohydrates​ (carbs), and 4 glasses of milk and 2 snack bars have a total of 86 carbs.

Answer 1

2M +3B = 73

4M +2B = 86

4M+6B = 146

4M+2B = 86

4B = 60

B = 15 carbs

2M = 73-3B =73-45 = 28

M = 28/2 = 14 carbs
