Natalie had some juice. Each day, she drank an equal amount of juice. At the end of the ninth day, she had 1700 mℓ of juice left. At the end of the tenth day, she had 1300 mℓ of juice left.
- What was the amount of juice she drank each day?
- How much juice did Natalie have at first? Give your answer in litres and millilitres.
(a)
Volume of juice that Natalie drank each day
= 1700 - 1300
= 400 mℓ
(b)
Volume of juice that Natalie had at first
= 1700 + 400 x 9
= 1700 + 3600
= 5300 mℓ
1000 mℓ = 1 ℓ
5300 mℓ = 5 ℓ 300 mℓ
Volume of juice that Natalie had at first = 5 ℓ 300 mℓ
Answer(s): (a) 400 mℓ; (b) 5 ℓ 300 mℓ
