- 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 H?
- Team G sold as many cups of iced milo as Team J but collected $8 less. How many small cups of iced milo did Team J sell?
(a)
Amount collected by Team F
= 17 x 3 + 3 x 7
= 51 + 21
= $72
Amount collected by Team G
= 11 x 3 + 9 x 7
= 33 + 63
= $96
Amount collected by Team H
= 6 x 3 + 11 x 7
= 18 + 77
= $95
Team F collected the least money.
(b)
Amount collected by Team H = $95
(c)

Since Team G and Team J sold the same number of cups but Team G collected $8 less, it means that Team J sold more big cups than Team G.
Difference in the total amount collected between Team G and Team J = $8
Difference in the amount collected for every one extra big cup sold by Team J
= 7 - 3
= $4
Number of extra big cups sold by Team J
= 8 ÷ 4
= 2
Number of small cups sold by Team J
= 11 - 2
= 9
Answer(s): (a) F; (b) $95; (c) 9
