- 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 french fries as Team U but collected $32 more. How many big cups of french fries did Team X sell?
(a)
Amount collected by Team U
= 16 x 5 + 2 x 9
= 80 + 18
= $98
Amount collected by Team V
= 12 x 5 + 9 x 9
= 60 + 81
= $141
Amount collected by Team W
= 7 x 5 + 10 x 9
= 35 + 90
= $125
Team V collected the most money.
(b)
Amount collected by Team U = $98
(c)

Since Team X and Team U sold the same number of cups but Team U collected $32 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 = $32
Difference in the amount collected for every one extra big cup sold by Team X
= 9 - 5
= $4
Number of extra big cups sold by Team X
= 32 ÷ 4
= 8
Number of big cups sold by Team X
= 2 + 8
= 10
Answer(s): (a) V; (b) $98; (c) 10
