- Which of the three teams collected the least money? Give your answer in letter. (Eg A)
- What was the amount of money collected by Team V?
- Team U sold as many cups of french fries as Team W but collected $16 less. How many small cups of french fries did Team W sell?
(a)
Amount collected by Team T
= 18 x 6 + 2 x 8
= 108 + 16
= $124
Amount collected by Team U
= 13 x 6 + 9 x 8
= 78 + 72
= $150
Amount collected by Team V
= 7 x 6 + 13 x 8
= 42 + 104
= $146
Team T collected the least money.
(b)
Amount collected by Team V = $146
(c)

150 + 16 = $166 |
Since Team U and Team W sold the same number of cups but Team U collected $16 less, it means that Team W sold more big cups than Team U.
Difference in the total amount collected between Team U and Team W = $16
Difference in the amount collected for every one extra big cup sold by Team W
= 8 - 6
= $2
Number of extra big cups sold by Team W
= 16 ÷ 2
= 8
Number of small cups sold by Team W
= 13 - 8
= 5
Answer(s): (a) T; (b) $146; (c) 5
