Natalie had some tea. Each day, she drank an equal amount of tea. At the end of the eighth day, she had 1600 mℓ of tea left. At the end of the ninth day, she had 1200 mℓ of tea left.
- What was the amount of tea she drank each day?
- How much tea did Natalie have at first? Give your answer in litres and millilitres.
(a)
Volume of tea that Natalie drank each day
= 1600 - 1200
= 400 mℓ
(b)
Volume of tea that Natalie had at first
= 1600 + 400 x 8
= 1600 + 3200
= 4800 mℓ
1000 mℓ = 1 ℓ
4800 mℓ = 4 ℓ 800 mℓ
Volume of tea that Natalie had at first = 4 ℓ 800 mℓ
Answer(s): (a) 400 mℓ; (b) 4 ℓ 800 mℓ
