The carton of milk was full. For a cooking recipe, 250 milliliters of this milk were used. How many milliliters of milk are still in the carton? Explain.

The amount of milk remaining in the cartons = a - 250

Step-by-step explanation:

The carton of milk was full . 250 millilitres of this milk were used for a cooking recipe. The millilitres of milk still remaining in the carton will be the actual millilitres of milk in the complete carton minus the 250 millilitres of milk used for the cooking recipe.

Let

amount of milk in the full carton = a millilitres (recall the question said the carton was filled with milk)

The amount of milk remaining in the cartons = amount of milk in the full cartons - 250 millilitres of milk used for cooking.

The amount of milk remaining in the cartons = a - 250

it would be 6xy and -16xy.
