Shiyun had some orange juice. Each day, she drank an equal amount of orange juice. At the end of the fourth day, she had 1500 mℓ of orange juice left. At the end of the fifth day, she had 1000 mℓ of orange juice left.
- What was the amount of orange juice she drank each day?
- How much orange juice did Shiyun have at first? Give your answer in litres and millilitres.
(a)
Volume of orange juice that Shiyun drank each day
= 1500 - 1000
= 500 mℓ
(b)
Volume of orange juice that Shiyun had at first
= 1500 + 500 x 4
= 1500 + 2000
= 3500 mℓ
1000 mℓ = 1 ℓ
3500 mℓ = 3 ℓ 500 mℓ
Volume of orange juice that Shiyun had at first = 3 ℓ 500 mℓ
Answer(s): (a) 500 mℓ; (b) 3 ℓ 500 mℓ
