- 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 T?
- Team W sold as many cups of french fries as Team T but collected $8 more. How many big cups of french fries did Team W sell?
(a)
Amount collected by Team T
= 15 x 8 + 2 x 10
= 120 + 20
= $140
Amount collected by Team U
= 12 x 8 + 8 x 10
= 96 + 80
= $176
Amount collected by Team V
= 9 x 8 + 10 x 10
= 72 + 100
= $172
Team U collected the most money.
(b)
Amount collected by Team T = $140
(c)

140 + 8 = $148 |
Since Team W and Team T sold the same number of cups but Team T collected $8 more, it means that Team W sold more big cups than Team T.
Difference in the total amount collected between Team W and Team T = $8
Difference in the amount collected for every one extra big cup sold by Team W
= 10 - 8
= $2
Number of extra big cups sold by Team W
= 8 ÷ 2
= 4
Number of big cups sold by Team W
= 2 + 4
= 6
Answer(s): (a) U; (b) $140; (c) 6
