Dana had some tea. Each day, she drank an equal amount of tea. At the end of the second day, she had 1500 mℓ of tea left. At the end of the third day, she had 1200 mℓ of tea left.
- What was the amount of tea she drank each day?
- How much tea did Dana have at first? Give your answer in litres and millilitres.
(a)
Volume of tea that Dana drank each day
= 1500 - 1200
= 300 mℓ
(b)
Volume of tea that Dana had at first
= 1500 + 300 x 2
= 1500 + 600
= 2100 mℓ
1000 mℓ = 1 ℓ
2100 mℓ = 2 ℓ 100 mℓ
Volume of tea that Dana had at first = 2 ℓ 100 mℓ
Answer(s): (a) 300 mℓ; (b) 2 ℓ 100 mℓ
