- 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 ice cream as Team V but collected $12 more. How many big cups of ice cream did Team Y sell?
(a)
Amount collected by Team V
= 18 x 5 + 2 x 9
= 90 + 18
= $108
Amount collected by Team W
= 13 x 5 + 8 x 9
= 65 + 72
= $137
Amount collected by Team X
= 8 x 5 + 10 x 9
= 40 + 90
= $130
Team W collected the most money.
(b)
Amount collected by Team V = $108
(c)

108 + 12 = $120 |
Since Team Y and Team V sold the same number of cups but Team V collected $12 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 = $12
Difference in the amount collected for every one extra big cup sold by Team Y
= 9 - 5
= $4
Number of extra big cups sold by Team Y
= 12 ÷ 4
= 3
Number of big cups sold by Team Y
= 2 + 3
= 5
Answer(s): (a) W; (b) $108; (c) 5
