- 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 U?
- Team T sold as many cups of lemonade as Team V but collected $24 less. How many small cups of lemonade did Team V sell?
(a)
Amount collected by Team S
= 17 x 3 + 3 x 6
= 51 + 18
= $69
Amount collected by Team T
= 14 x 3 + 9 x 6
= 42 + 54
= $96
Amount collected by Team U
= 7 x 3 + 10 x 6
= 21 + 60
= $81
Team S collected the least money.
(b)
Amount collected by Team U = $81
(c)

Since Team T and Team V sold the same number of cups but Team T collected $24 less, it means that Team V sold more big cups than Team T.
Difference in the total amount collected between Team T and Team V = $24
Difference in the amount collected for every one extra big cup sold by Team V
= 6 - 3
= $3
Number of extra big cups sold by Team V
= 24 ÷ 3
= 8
Number of small cups sold by Team V
= 14 - 8
= 6
Answer(s): (a) S; (b) $81; (c) 6
