Sofia poured 909 mℓ of fruit punch into a cup, a bottle and a mug. The cup contained 3 times as much fruit punch as the bottle. The mug contained 121 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 = 3 u
Volume of fruit punch that a bottle contained = 1 u
Volume of fruit punch that a mug contained = 121 mℓ
Total volume of fruit punch
= 3 u + 1 u + 121
= 4 u + 121
4 u + 121 = 909
4 u = 909 - 121
4 u = 788
1 u = 788 ÷ 4 = 197
Volume of fruit punch the bottle contained
= 1 u
= 197 mℓ
(b)
Amount of fruit punch that the cup contained more than the mug
= 3 u - 121
= (3 x 197) - 121
= 591 - 121
= 470 mℓ
Answer(s): (a) 197 mℓ; (b) 470 mℓ
