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 T	17	2
Team U	13	9
Team V	6	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 T?
3. Team W sold as many cups of french fries as Team T but collected $16 more. How many big cups of french fries did Team W sell?

(a)
Amount collected by Team T = 85 + 18
= $103

Amount collected by Team U
= 13 x 5 + 9 x 9
= 65 + 81
= $146

Amount collected by Team V
= 6 x 5 + 10 x 9
= 30 + 90
= $120

Team U collected the most money.

(b)
Amount collected by Team T = $103

(c)

	Small cups	Big cups	Total cups	Total amount
Team T	17	2	19	$103
Team W	13	6	19	103 + 16 = $119

Since Team W and Team T sold the same number of cups but Team T collected $16 more, it means that Team W sold more big cups than Team T.

Difference in the total amount collected between Team W and Team T = $16

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

Number of extra big cups sold by Team W
= 16 ÷ 4
= 4

Number of big cups sold by Team W
= 2 + 4
= 6

Answer(s): (a) U; (b) $103; (c) 6
