Jean had some soy milk. Each day, she drank an equal amount of soy milk. At the end of the eighth day, she had 1400 mℓ of soy milk left. At the end of the ninth day, she had 1300 mℓ of soy milk left.
- What was the amount of soy milk she drank each day?
- How much soy milk did Jean have at first? Give your answer in litres and millilitres.
(a)
Volume of soy milk that Jean drank each day
= 1400 - 1300
= 100 mℓ
(b)
Volume of soy milk that Jean had at first
= 1400 + 100 x 8
= 1400 + 800
= 2200 mℓ
1000 mℓ = 1 ℓ
2200 mℓ = 2 ℓ 200 mℓ
Volume of soy milk that Jean had at first = 2 ℓ 200 mℓ
Answer(s): (a) 100 mℓ; (b) 2 ℓ 200 mℓ
