Four teams of students sold nuggets for charity.
They collected $5 for a small cup of nuggets and $7 for a big cup of nuggets.

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

	Small cups	Big cups
Team V	19	2
Team W	14	9
Team X	10	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 V?
3. Team Y sold as many cups of nuggets as Team V but collected $16 more. How many big cups of nuggets did Team Y sell?

(a)
Amount collected by Team V = 95 + 14
= $109

Amount collected by Team W
= 14 x 5 + 9 x 7
= 70 + 63
= $133

Amount collected by Team X
= 10 x 5 + 10 x 7
= 50 + 70
= $120

Team W collected the most money.

(b)
Amount collected by Team V = $109

(c)

	Small cups	Big cups	Total cups	Total amount
Team V	19	2	21	$109
Team Y	11	10	21	109 + 16 = $125

Since Team Y and Team V sold the same number of cups but Team V collected $16 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 = $16

Difference in the amount collected for every one extra big cup sold by Team Y
= 7 - 5
= $2

Number of extra big cups sold by Team Y
= 16 ÷ 2
= 8

Number of big cups sold by Team Y
= 2 + 8
= 10

Answer(s): (a) W; (b) $109; (c) 10
