Natalie had some soy milk. Each day, she drank an equal amount of soy milk. At the end of the eighth day, she had 1500 mℓ of soy milk left. At the end of the ninth day, she had 1000 mℓ of soy milk left.
- What was the amount of soy milk she drank each day?
- How much soy milk did Natalie have at first? Give your answer in litres and millilitres.
(a)
Volume of soy milk that Natalie drank each day
= 1500 - 1000
= 500 mℓ
(b)
Volume of soy milk that Natalie had at first
= 1500 + 500 x 8
= 1500 + 4000
= 5500 mℓ
1000 mℓ = 1 ℓ
5500 mℓ = 5 ℓ 500 mℓ
Volume of soy milk that Natalie had at first = 5 ℓ 500 mℓ
Answer(s): (a) 500 mℓ; (b) 5 ℓ 500 mℓ
