Roshel had some juice. Each day, she drank an equal amount of juice. At the end of the seventh day, she had 1300 mℓ of juice left. At the end of the eighth day, she had 1000 mℓ of juice left.
- What was the amount of juice she drank each day?
- How much juice did Roshel have at first? Give your answer in litres and millilitres.
(a)
Volume of juice that Roshel drank each day
= 1300 - 1000
= 300 mℓ
(b)
Volume of juice that Roshel had at first
= 1300 + 300 x 7
= 1300 + 2100
= 3400 mℓ
1000 mℓ = 1 ℓ
3400 mℓ = 3 ℓ 400 mℓ
Volume of juice that Roshel had at first = 3 ℓ 400 mℓ
Answer(s): (a) 300 mℓ; (b) 3 ℓ 400 mℓ
