Four teams of students sold iced milo for charity.
They collected $6 for a small cup of iced milo and $8 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 M	17	2
Team N	13	8
Team P	6	13

1. Which of the three teams collected the least money? Give your answer in letter. (Eg A)
2. What was the amount of money collected by Team P?
3. Team N sold as many cups of iced milo as Team Q but collected $14 less. How many small cups of iced milo did Team Q sell?

(a)
Amount collected by Team M = 102 + 16
= $118

Amount collected by Team N
= 13 x 6 + 8 x 8
= 78 + 64
= $142

Amount collected by Team P
= 6 x 6 + 13 x 8
= 36 + 104
= $140

Team M collected the least money.

(b)
Amount collected by Team P = $140

(c)

	Small cups	Big cups	Total cups	Total amount
Team N	13	8	21	$142
Team Q	6	15	21	142 + 14 = $156

Since Team N and Team Q sold the same number of cups but Team N collected $14 less, it means that Team Q sold more big cups than Team N.

Difference in the total amount collected between Team N and Team Q = $14

Difference in the amount collected for every one extra big cup sold by Team Q
= 8 - 6
= $2

Number of extra big cups sold by Team Q
= 14 ÷ 2
= 7

Number of small cups sold by Team Q
= 13 - 7
= 6

Answer(s): (a) M; (b) $140; (c) 6
