- 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 V?
- Team Y sold as many cups of french fries as Team V but collected $10 more. How many big cups of french fries did Team Y sell?
(a)
Amount collected by Team V
= 17 x 8 + 2 x 10
= 136 + 20
= $156
Amount collected by Team W
= 14 x 8 + 6 x 10
= 112 + 60
= $172
Amount collected by Team X
= 7 x 8 + 11 x 10
= 56 + 110
= $166
Team W collected the most money.
(b)
Amount collected by Team V = $156
(c)

Since Team Y and Team V sold the same number of cups but Team V collected $10 more, it means that Team Y sold more big cups than Team V.
Difference in the total amount collected between Team Y and Team V = $10
Difference in the amount collected for every one extra big cup sold by Team Y
= 10 - 8
= $2
Number of extra big cups sold by Team Y
= 10 ÷ 2
= 5
Number of big cups sold by Team Y
= 2 + 5
= 7
Answer(s): (a) W; (b) $156; (c) 7
