- Which of the three teams collected the most money? Give your answer in letter. (Eg A)
- What was the amount of money collected by Team R?
- Team U sold as many cups of lemonade as Team R but collected $6 more. How many big cups of lemonade did Team U sell?
(a)
Amount collected by Team R
= 16 x 5 + 3 x 8
= 80 + 24
= $104
Amount collected by Team S
= 14 x 5 + 7 x 8
= 70 + 56
= $126
Amount collected by Team T
= 9 x 5 + 10 x 8
= 45 + 80
= $125
Team S collected the most money.
(b)
Amount collected by Team R = $104
(c)

Since Team U and Team R sold the same number of cups but Team R collected $6 more, it means that Team U sold more big cups than Team R.
Difference in the total amount collected between Team U and Team R = $6
Difference in the amount collected for every one extra big cup sold by Team U
= 8 - 5
= $3
Number of extra big cups sold by Team U
= 6 ÷ 3
= 2
Number of big cups sold by Team U
= 3 + 2
= 5
Answer(s): (a) S; (b) $104; (c) 5
