- 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 G?
- Team K sold as many cups of lemonade as Team G but collected $10 more. How many big cups of lemonade did Team K sell?
(a)
Amount collected by Team G
= 19 x 6 + 2 x 8
= 114 + 16
= $130
Amount collected by Team H
= 14 x 6 + 8 x 8
= 84 + 64
= $148
Amount collected by Team J
= 7 x 6 + 13 x 8
= 42 + 104
= $146
Team H collected the most money.
(b)
Amount collected by Team G = $130
(c)

130 + 10 = $140 |
Since Team K and Team G sold the same number of cups but Team G collected $10 more, it means that Team K sold more big cups than Team G.
Difference in the total amount collected between Team K and Team G = $10
Difference in the amount collected for every one extra big cup sold by Team K
= 8 - 6
= $2
Number of extra big cups sold by Team K
= 10 ÷ 2
= 5
Number of big cups sold by Team K
= 2 + 5
= 7
Answer(s): (a) H; (b) $130; (c) 7
