- 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 M?
- Team Q sold as many cups of ice cream as Team M but collected $10 more. How many big cups of ice cream did Team Q sell?
(a)
Amount collected by Team M
= 15 x 6 + 3 x 8
= 90 + 24
= $114
Amount collected by Team N
= 13 x 6 + 9 x 8
= 78 + 72
= $150
Amount collected by Team P
= 6 x 6 + 13 x 8
= 36 + 104
= $140
Team N collected the most money.
(b)
Amount collected by Team M = $114
(c)

Since Team Q and Team M sold the same number of cups but Team M collected $10 more, it means that Team Q sold more big cups than Team M.
Difference in the total amount collected between Team Q and Team M = $10
Difference in the amount collected for every one extra big cup sold by Team Q
= 8 - 6
= $2
Number of extra big cups sold by Team Q
= 10 ÷ 2
= 5
Number of big cups sold by Team Q
= 3 + 5
= 8
Answer(s): (a) N; (b) $114; (c) 8
