Gabby had some orange juice. Each day, she drank an equal amount of orange juice. At the end of the sixth day, she had 1700 mℓ of orange juice left. At the end of the seventh day, she had 1300 mℓ of orange juice left.
- What was the amount of orange juice she drank each day?
- How much orange juice did Gabby have at first? Give your answer in litres and millilitres.
(a)
Volume of orange juice that Gabby drank each day
= 1700 - 1300
= 400 mℓ
(b)
Volume of orange juice that Gabby had at first
= 1700 + 400 x 6
= 1700 + 2400
= 4100 mℓ
1000 mℓ = 1 ℓ
4100 mℓ = 4 ℓ 100 mℓ
Volume of orange juice that Gabby had at first = 4 ℓ 100 mℓ
Answer(s): (a) 400 mℓ; (b) 4 ℓ 100 mℓ
