Four teams of students sold iced milo for charity.
They collected $6 for a small cup of iced milo and $8 for a big cup of iced milo.

The table shows the number of cups sold by three of the teams.

	Small cups	Big cups
Team G	15	2
Team H	13	7
Team J	7	10

1. Which of the three teams collected the most money? Give your answer in letter. (Eg A)
2. What was the amount of money collected by Team G?
3. Team K sold as many cups of iced milo as Team G but collected $6 more. How many big cups of iced milo did Team K sell?

(a)
Amount collected by Team G = 90 + 16
= $106

Amount collected by Team H
= 13 x 6 + 7 x 8
= 78 + 56
= $134

Amount collected by Team J
= 7 x 6 + 10 x 8
= 42 + 80
= $122

Team H collected the most money.

(b)
Amount collected by Team G = $106

(c)

	Small cups	Big cups	Total cups	Total amount
Team G	15	2	17	$106
Team K	12	5	17	106 + 6 = $112

Since Team K and Team G sold the same number of cups but Team G collected $6 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 = $6

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
= 6 ÷ 2
= 3

Number of big cups sold by Team K
= 2 + 3
= 5

Answer(s): (a) H; (b) $106; (c) 5
