Four teams of students sold iced milo for charity.
They collected $2 for a small cup of iced milo and $6 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 D	15	4
Team E	13	9
Team F	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 D?
3. Team G sold as many cups of iced milo as Team D but collected $12 more. How many big cups of iced milo did Team G sell?

(a)
Amount collected by Team D = 30 + 24
= $54

Amount collected by Team E
= 13 x 2 + 9 x 6
= 26 + 54
= $80

Amount collected by Team F
= 7 x 2 + 10 x 6
= 14 + 60
= $74

Team E collected the most money.

(b)
Amount collected by Team D = $54

(c)

	Small cups	Big cups	Total cups	Total amount
Team D	15	4	19	$54
Team G	12	7	19	54 + 12 = $66

Since Team G and Team D sold the same number of cups but Team D collected $12 more, it means that Team G sold more big cups than Team D.

Difference in the total amount collected between Team G and Team D = $12

Difference in the amount collected for every one extra big cup sold by Team G
= 6 - 2
= $4

Number of extra big cups sold by Team G
= 12 ÷ 4
= 3

Number of big cups sold by Team G
= 4 + 3
= 7

Answer(s): (a) E; (b) $54; (c) 7
