Four teams of students sold nuggets for charity.
They collected $5 for a small cup of nuggets and $8 for a big cup of nuggets.

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

	Small cups	Big cups
Team N	16	4
Team P	12	9
Team Q	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 N?
3. Team R sold as many cups of nuggets as Team N but collected $21 more. How many big cups of nuggets did Team R sell?

(a)
Amount collected by Team N = 80 + 32
= $112

Amount collected by Team P
= 12 x 5 + 9 x 8
= 60 + 72
= $132

Amount collected by Team Q
= 6 x 5 + 11 x 8
= 30 + 88
= $118

Team P collected the most money.

(b)
Amount collected by Team N = $112

(c)

	Small cups	Big cups	Total cups	Total amount
Team N	16	4	20	$112
Team R	9	11	20	112 + 21 = $133

Since Team R and Team N sold the same number of cups but Team N collected $21 more, it means that Team R sold more big cups than Team N.

Difference in the total amount collected between Team R and Team N = $21

Difference in the amount collected for every one extra big cup sold by Team R
= 8 - 5
= $3

Number of extra big cups sold by Team R
= 21 ÷ 3
= 7

Number of big cups sold by Team R
= 4 + 7
= 11

Answer(s): (a) P; (b) $112; (c) 11
