- 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 P?
- Team S sold as many cups of ice cream as Team P but collected $8 more. How many big cups of ice cream did Team S sell?
(a)
Amount collected by Team P
= 16 x 6 + 2 x 8
= 96 + 16
= $112
Amount collected by Team Q
= 12 x 6 + 9 x 8
= 72 + 72
= $144
Amount collected by Team R
= 6 x 6 + 10 x 8
= 36 + 80
= $116
Team Q collected the most money.
(b)
Amount collected by Team P = $112
(c)

Since Team S and Team P sold the same number of cups but Team P collected $8 more, it means that Team S sold more big cups than Team P.
Difference in the total amount collected between Team S and Team P = $8
Difference in the amount collected for every one extra big cup sold by Team S
= 8 - 6
= $2
Number of extra big cups sold by Team S
= 8 ÷ 2
= 4
Number of big cups sold by Team S
= 2 + 4
= 6
Answer(s): (a) Q; (b) $112; (c) 6
