Linda bought 5 cartons of orange juice. Each carton contained 980 ml of orange juice. Her children drank 500 ml of orange juice daily from Monday to Sunday. How much orange juice did she have left at the end of the week?
L ml
The total orange juice: 980 ml × 5 = 4900 ml
The orange juice consumed: 500 ml × 7 = 3500 ml
Thus, the remaining amount: 4900 ml - 3500 ml = 1400 ml = 1 L 400 ml
