Two glasses of milk and 3 snack bars have a total of 61 carbohydrates​ (carbs), and 3 glasses of milk and 2 snack bars have a total of 64 carbs. Determine how many carbs are in one glass of milk and in one snack bar.

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
