Gwen had some soy milk. Each day, she drank an equal amount of soy milk. At the end of the sixth day, she had 1700 mℓ of soy milk left. At the end of the seventh day, she had 1600 mℓ of soy milk left.
- What was the amount of soy milk she drank each day?
- How much soy milk did Gwen have at first? Give your answer in litres and millilitres.
(a)
Volume of soy milk that Gwen drank each day
= 1700 - 1600
= 100 mℓ
(b)
Volume of soy milk that Gwen had at first
= 1700 + 100 x 6
= 1700 + 600
= 2300 mℓ
1000 mℓ = 1 ℓ
2300 mℓ = 2 ℓ 300 mℓ
Volume of soy milk that Gwen had at first = 2 ℓ 300 mℓ
Answer(s): (a) 100 mℓ; (b) 2 ℓ 300 mℓ
