Four teams of students sold nuggets for charity.
They collected $7 for a small cup of nuggets and $9 for a big cup of nuggets.

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

	Small cups	Big cups
Team H	18	3
Team J	12	9
Team K	7	12

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 K?
3. Team J sold as many cups of nuggets as Team L but collected $12 less. How many small cups of nuggets did Team L sell?

(a)
Amount collected by Team H = 126 + 27
= $153

Amount collected by Team J
= 12 x 7 + 9 x 9
= 84 + 81
= $165

Amount collected by Team K
= 7 x 7 + 12 x 9
= 49 + 108
= $157

Team H collected the least money.

(b)
Amount collected by Team K = $157

(c)

	Small cups	Big cups	Total cups	Total amount
Team J	12	9	21	$165
Team L	6	15	21	165 + 12 = $177

Since Team J and Team L sold the same number of cups but Team J collected $12 less, it means that Team L sold more big cups than Team J.

Difference in the total amount collected between Team J and Team L = $12

Difference in the amount collected for every one extra big cup sold by Team L
= 9 - 7
= $2

Number of extra big cups sold by Team L
= 12 ÷ 2
= 6

Number of small cups sold by Team L
= 12 - 6
= 6

Answer(s): (a) H; (b) $157; (c) 6
