- 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 L?
- Team P sold as many cups of ice cream as Team L but collected $10 more. How many big cups of ice cream did Team P sell?
(a)
Amount collected by Team L
= 15 x 5 + 4 x 7
= 75 + 28
= $103
Amount collected by Team M
= 13 x 5 + 8 x 7
= 65 + 56
= $121
Amount collected by Team N
= 7 x 5 + 11 x 7
= 35 + 77
= $112
Team M collected the most money.
(b)
Amount collected by Team L = $103
(c)

103 + 10 = $113 |
Since Team P and Team L sold the same number of cups but Team L collected $10 more, it means that Team P sold more big cups than Team L.
Difference in the total amount collected between Team P and Team L = $10
Difference in the amount collected for every one extra big cup sold by Team P
= 7 - 5
= $2
Number of extra big cups sold by Team P
= 10 ÷ 2
= 5
Number of big cups sold by Team P
= 4 + 5
= 9
Answer(s): (a) M; (b) $103; (c) 9
