- Which of the three teams collected the least money? Give your answer in letter. (Eg A)
- What was the amount of money collected by Team J?
- Team H sold as many cups of iced milo as Team K but collected $16 less. How many small cups of iced milo did Team K sell?
(a)
Amount collected by Team G
= 16 x 4 + 3 x 8
= 64 + 24
= $88
Amount collected by Team H
= 13 x 4 + 8 x 8
= 52 + 64
= $116
Amount collected by Team J
= 6 x 4 + 10 x 8
= 24 + 80
= $104
Team G collected the least money.
(b)
Amount collected by Team J = $104
(c)

116 + 16 = $132 |
Since Team H and Team K sold the same number of cups but Team H collected $16 less, it means that Team K sold more big cups than Team H.
Difference in the total amount collected between Team H and Team K = $16
Difference in the amount collected for every one extra big cup sold by Team K
= 8 - 4
= $4
Number of extra big cups sold by Team K
= 16 ÷ 4
= 4
Number of small cups sold by Team K
= 13 - 4
= 9
Answer(s): (a) G; (b) $104; (c) 9
