- 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 U?
- Team X sold as many cups of nuggets as Team U but collected $12 more. How many big cups of nuggets did Team X sell?
(a)
Amount collected by Team U
= 15 x 8 + 3 x 10
= 120 + 30
= $150
Amount collected by Team V
= 13 x 8 + 9 x 10
= 104 + 90
= $194
Amount collected by Team W
= 8 x 8 + 11 x 10
= 64 + 110
= $174
Team V collected the most money.
(b)
Amount collected by Team U = $150
(c)

Since Team X and Team U sold the same number of cups but Team U collected $12 more, it means that Team X sold more big cups than Team U.
Difference in the total amount collected between Team X and Team U = $12
Difference in the amount collected for every one extra big cup sold by Team X
= 10 - 8
= $2
Number of extra big cups sold by Team X
= 12 ÷ 2
= 6
Number of big cups sold by Team X
= 3 + 6
= 9
Answer(s): (a) V; (b) $150; (c) 9
