Marion had some soy milk. Each day, she drank an equal amount of soy milk. At the end of the fifth day, she had 1500 mℓ of soy milk left. At the end of the sixth day, she had 1100 mℓ of soy milk left.
- What was the amount of soy milk she drank each day?
- How much soy milk did Marion have at first? Give your answer in litres and millilitres.
(a)
Volume of soy milk that Marion drank each day
= 1500 - 1100
= 400 mℓ
(b)
Volume of soy milk that Marion had at first
= 1500 + 400 x 5
= 1500 + 2000
= 3500 mℓ
1000 mℓ = 1 ℓ
3500 mℓ = 3 ℓ 500 mℓ
Volume of soy milk that Marion had at first = 3 ℓ 500 mℓ
Answer(s): (a) 400 mℓ; (b) 3 ℓ 500 mℓ
