Scarlett poured 1121 mℓ of fruit punch into a mug, a bottle and a cup. The mug contained 2 times as much fruit punch as the bottle. The cup contained 131 mℓ of fruit punch.
- How much fruit punch did the bottle contain?
- How much more fruit punch did the mug contain than the cup?
(a)
Volume of fruit punch that a mug contained = 2 u
Volume of fruit punch that a bottle contained = 1 u
Volume of fruit punch that a cup contained = 131 mℓ
Total volume of fruit punch
= 2 u + 1 u + 131
= 3 u + 131
3 u + 131 = 1121
3 u = 1121 - 131
3 u = 990
1 u = 990 ÷ 3 = 330
Volume of fruit punch the bottle contained
= 1 u
= 330 mℓ
(b)
Amount of fruit punch that the mug contained more than the cup
= 2 u - 131
= (2 x 330) - 131
= 660 - 131
= 529 mℓ
Answer(s): (a) 330 mℓ; (b) 529 mℓ
