- 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 S?
- Team V sold as many cups of soda as Team S but collected $8 more. How many big cups of soda did Team V sell?
(a)
Amount collected by Team S
= 15 x 6 + 4 x 10
= 90 + 40
= $130
Amount collected by Team T
= 13 x 6 + 6 x 10
= 78 + 60
= $138
Amount collected by Team U
= 6 x 6 + 10 x 10
= 36 + 100
= $136
Team T collected the most money.
(b)
Amount collected by Team S = $130
(c)

130 + 8 = $138 |
Since Team V and Team S sold the same number of cups but Team S collected $8 more, it means that Team V sold more big cups than Team S.
Difference in the total amount collected between Team V and Team S = $8
Difference in the amount collected for every one extra big cup sold by Team V
= 10 - 6
= $4
Number of extra big cups sold by Team V
= 8 ÷ 4
= 2
Number of big cups sold by Team V
= 4 + 2
= 6
Answer(s): (a) T; (b) $130; (c) 6
