Tiffany had some orange juice. Each day, she drank an equal amount of orange juice. At the end of the fourth day, she had 1400 mℓ of orange juice left. At the end of the fifth day, she had 1300 mℓ of orange juice left.
- What was the amount of orange juice she drank each day?
- How much orange juice did Tiffany have at first? Give your answer in litres and millilitres.
(a)
Volume of orange juice that Tiffany drank each day
= 1400 - 1300
= 100 mℓ
(b)
Volume of orange juice that Tiffany had at first
= 1400 + 100 x 4
= 1400 + 400
= 1800 mℓ
1000 mℓ = 1 ℓ
1800 mℓ = 1 ℓ 800 mℓ
Volume of orange juice that Tiffany had at first = 1 ℓ 800 mℓ
Answer(s): (a) 100 mℓ; (b) 1 ℓ 800 mℓ
