Nora had some orange juice. Each day, she drank an equal amount of orange juice. At the end of the fifth day, she had 1600 mℓ of orange juice left. At the end of the sixth day, she had 1100 mℓ of orange juice left.
- What was the amount of orange juice she drank each day?
- How much orange juice did Nora have at first? Give your answer in litres and millilitres.
(a)
Volume of orange juice that Nora drank each day
= 1600 - 1100
= 500 mℓ
(b)
Volume of orange juice that Nora had at first
= 1600 + 500 x 5
= 1600 + 2500
= 4100 mℓ
1000 mℓ = 1 ℓ
4100 mℓ = 4 ℓ 100 mℓ
Volume of orange juice that Nora had at first = 4 ℓ 100 mℓ
Answer(s): (a) 500 mℓ; (b) 4 ℓ 100 mℓ
