Gavin poured 725 mℓ of fruit punch into a cup, a bottle and a mug. The cup contained 4 times as much fruit punch as the bottle. The mug contained 100 mℓ of fruit punch.
- How much fruit punch did the bottle contain?
- How much more fruit punch did the cup contain than the mug?
(a)
Volume of fruit punch that a cup contained = 4 u
Volume of fruit punch that a bottle contained = 1 u
Volume of fruit punch that a mug contained = 100 mℓ
Total volume of fruit punch
= 4 u + 1 u + 100
= 5 u + 100
5 u + 100 = 725
5 u = 725 - 100
5 u = 625
1 u = 625 ÷ 5 = 125
Volume of fruit punch the bottle contained
= 1 u
= 125 mℓ
(b)
Amount of fruit punch that the cup contained more than the mug
= 4 u - 100
= (4 x 125) - 100
= 500 - 100
= 400 mℓ
Answer(s): (a) 125 mℓ; (b) 400 mℓ
