gallon

Every Sunday morning Maria checks the fridge and pantry to estimate how much milk and juice they will need for the week . She knows that a gallon of milk is roughly 3.8 liters , so when the carton looks half empty she plans to buy another to avoid last - minute trips . At the supermarket she compares prices and checks expiry dates before selecting the larger container because it is often more economical for their household . If the children are visiting , she also buys an extra bottle of juice and pours it into a jug so the portions are easier to serve . By organizing supplies this way she reduces waste and feels more confident about the week's meals .
