Irene had some tea. Each day, she drank an equal amount of tea. At the end of the third day, she had 1300 mℓ of tea left. At the end of the fourth day, she had 1000 mℓ of tea left.
- What was the amount of tea she drank each day?
- How much tea did Irene have at first? Give your answer in litres and millilitres.
(a)
Volume of tea that Irene drank each day
= 1300 - 1000
= 300 mℓ
(b)
Volume of tea that Irene had at first
= 1300 + 300 x 3
= 1300 + 900
= 2200 mℓ
1000 mℓ = 1 ℓ
2200 mℓ = 2 ℓ 200 mℓ
Volume of tea that Irene had at first = 2 ℓ 200 mℓ
Answer(s): (a) 300 mℓ; (b) 2 ℓ 200 mℓ
