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 P	17	2
Team Q	14	6
Team R	7	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 P?
3. Team S sold as many cups of nuggets as Team P but collected $18 more. How many big cups of nuggets did Team S sell?

(a)
Amount collected by Team P = 85 + 16
= $101

Amount collected by Team Q
= 14 x 5 + 6 x 8
= 70 + 48
= $118

Amount collected by Team R
= 7 x 5 + 10 x 8
= 35 + 80
= $115

Team Q collected the most money.

(b)
Amount collected by Team P = $101

(c)

	Small cups	Big cups	Total cups	Total amount
Team P	17	2	19	$101
Team S	11	8	19	101 + 18 = $119

Since Team S and Team P sold the same number of cups but Team P collected $18 more, it means that Team S sold more big cups than Team P.

Difference in the total amount collected between Team S and Team P = $18

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

Number of extra big cups sold by Team S
= 18 ÷ 3
= 6

Number of big cups sold by Team S
= 2 + 6
= 8

Answer(s): (a) Q; (b) $101; (c) 8
