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 V	16	3
Team W	13	9
Team X	6	11

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 V?
3. Team Y sold as many cups of iced milo as Team V but collected $28 more. How many big cups of iced milo did Team Y sell?

(a)
Amount collected by Team V = 32 + 18
= $50

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

Amount collected by Team X
= 6 x 2 + 11 x 6
= 12 + 66
= $78

Team W collected the most money.

(b)
Amount collected by Team V = $50

(c)

	Small cups	Big cups	Total cups	Total amount
Team V	16	3	19	$50
Team Y	9	10	19	50 + 28 = $78

Since Team Y and Team V sold the same number of cups but Team V collected $28 more, it means that Team Y sold more big cups than Team V.

Difference in the total amount collected between Team Y and Team V = $28

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

Number of extra big cups sold by Team Y
= 28 ÷ 4
= 7

Number of big cups sold by Team Y
= 3 + 7
= 10

Answer(s): (a) W; (b) $50; (c) 10
