Marion had some soy milk. Each day, she drank an equal amount of soy milk. At the end of the eighth day, she had 1700 mℓ of soy milk left. At the end of the ninth 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
= 1700 - 1100
= 600 mℓ
(b)
Volume of soy milk that Marion had at first
= 1700 + 600 x 8
= 1700 + 4800
= 6500 mℓ
1000 mℓ = 1 ℓ
6500 mℓ = 6 ℓ 500 mℓ
Volume of soy milk that Marion had at first = 6 ℓ 500 mℓ
Answer(s): (a) 600 mℓ; (b) 6 ℓ 500 mℓ
