Julie poured 1135 mℓ of fruit punch into a cup, a glass and a mug. The cup contained 3 times as much fruit punch as the glass. The mug contained 143 mℓ of fruit punch.
- How much fruit punch did the glass 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 glass contained = 1 u
Volume of fruit punch that a mug contained = 143 mℓ
Total volume of fruit punch
= 3 u + 1 u + 143
= 4 u + 143
4 u + 143 = 1135
4 u = 1135 - 143
4 u = 992
1 u = 992 ÷ 4 = 248
Volume of fruit punch the glass contained
= 1 u
= 248 mℓ
(b)
Amount of fruit punch that the cup contained more than the mug
= 3 u - 143
= (3 x 248) - 143
= 744 - 143
= 601 mℓ
Answer(s): (a) 248 mℓ; (b) 601 mℓ
