Elizabeth poured 937 mℓ of fruit punch into a bottle, a cup and a glass. The bottle contained 3 times as much fruit punch as the cup. The glass contained 121 mℓ of fruit punch.
- How much fruit punch did the cup contain?
- How much more fruit punch did the bottle contain than the glass?
(a)
Volume of fruit punch that a bottle contained = 3 u
Volume of fruit punch that a cup contained = 1 u
Volume of fruit punch that a glass contained = 121 mℓ
Total volume of fruit punch
= 3 u + 1 u + 121
= 4 u + 121
4 u + 121 = 937
4 u = 937 - 121
4 u = 816
1 u = 816 ÷ 4 = 204
Volume of fruit punch the cup contained
= 1 u
= 204 mℓ
(b)
Amount of fruit punch that the bottle contained more than the glass
= 3 u - 121
= (3 x 204) - 121
= 612 - 121
= 491 mℓ
Answer(s): (a) 204 mℓ; (b) 491 mℓ
