- 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 H?
- Team L sold as many cups of ice cream as Team H but collected $21 more. How many big cups of ice cream did Team L sell?
(a)
Amount collected by Team H
= 17 x 6 + 3 x 9
= 102 + 27
= $129
Amount collected by Team J
= 14 x 6 + 8 x 9
= 84 + 72
= $156
Amount collected by Team K
= 9 x 6 + 11 x 9
= 54 + 99
= $153
Team J collected the most money.
(b)
Amount collected by Team H = $129
(c)

129 + 21 = $150 |
Since Team L and Team H sold the same number of cups but Team H collected $21 more, it means that Team L sold more big cups than Team H.
Difference in the total amount collected between Team L and Team H = $21
Difference in the amount collected for every one extra big cup sold by Team L
= 9 - 6
= $3
Number of extra big cups sold by Team L
= 21 ÷ 3
= 7
Number of big cups sold by Team L
= 3 + 7
= 10
Answer(s): (a) J; (b) $129; (c) 10
