Four teams of students sold french fries for charity.
They collected $5 for a small cup of french fries and $9 for a big cup of french fries.

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

	Small cups	Big cups
Team W	19	4
Team X	14	9
Team Y	6	13

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 W?
3. Team Z sold as many cups of french fries as Team W but collected $32 more. How many big cups of french fries did Team Z sell?

(a)
Amount collected by Team W = 95 + 36
= $131

Amount collected by Team X
= 14 x 5 + 9 x 9
= 70 + 81
= $151

Amount collected by Team Y
= 6 x 5 + 13 x 9
= 30 + 117
= $147

Team X collected the most money.

(b)
Amount collected by Team W = $131

(c)

	Small cups	Big cups	Total cups	Total amount
Team W	19	4	23	$131
Team Z	11	12	23	131 + 32 = $163

Since Team Z and Team W sold the same number of cups but Team W collected $32 more, it means that Team Z sold more big cups than Team W.

Difference in the total amount collected between Team Z and Team W = $32

Difference in the amount collected for every one extra big cup sold by Team Z
= 9 - 5
= $4

Number of extra big cups sold by Team Z
= 32 ÷ 4
= 8

Number of big cups sold by Team Z
= 4 + 8
= 12

Answer(s): (a) X; (b) $131; (c) 12
