Shiyun had some juice. Each day, she drank an equal amount of juice. At the end of the sixth day, she had 1600 mℓ of juice left. At the end of the seventh day, she had 1400 mℓ of juice left.
- What was the amount of juice she drank each day?
- How much juice did Shiyun have at first? Give your answer in litres and millilitres.
(a)
Volume of juice that Shiyun drank each day
= 1600 - 1400
= 200 mℓ
(b)
Volume of juice that Shiyun had at first
= 1600 + 200 x 6
= 1600 + 1200
= 2800 mℓ
1000 mℓ = 1 ℓ
2800 mℓ = 2 ℓ 800 mℓ
Volume of juice that Shiyun had at first = 2 ℓ 800 mℓ
Answer(s): (a) 200 mℓ; (b) 2 ℓ 800 mℓ
