- 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 E?
- Team H sold as many cups of ice cream as Team E but collected $20 more. How many big cups of ice cream did Team H sell?
(a)
Amount collected by Team E
= 15 x 4 + 2 x 8
= 60 + 16
= $76
Amount collected by Team F
= 14 x 4 + 8 x 8
= 56 + 64
= $120
Amount collected by Team G
= 7 x 4 + 10 x 8
= 28 + 80
= $108
Team F collected the most money.
(b)
Amount collected by Team E = $76
(c)

Since Team H and Team E sold the same number of cups but Team E collected $20 more, it means that Team H sold more big cups than Team E.
Difference in the total amount collected between Team H and Team E = $20
Difference in the amount collected for every one extra big cup sold by Team H
= 8 - 4
= $4
Number of extra big cups sold by Team H
= 20 ÷ 4
= 5
Number of big cups sold by Team H
= 2 + 5
= 7
Answer(s): (a) F; (b) $76; (c) 7
