Jane had some soy milk. Each day, she drank an equal amount of soy milk. At the end of the seventh day, she had 1300 mℓ of soy milk left. At the end of the eighth 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 Jane have at first? Give your answer in litres and millilitres.
(a)
Volume of soy milk that Jane drank each day
= 1300 - 1100
= 200 mℓ
(b)
Volume of soy milk that Jane had at first
= 1300 + 200 x 7
= 1300 + 1400
= 2700 mℓ
1000 mℓ = 1 ℓ
2700 mℓ = 2 ℓ 700 mℓ
Volume of soy milk that Jane had at first = 2 ℓ 700 mℓ
Answer(s): (a) 200 mℓ; (b) 2 ℓ 700 mℓ
