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 F	20	2
Team G	14	9
Team H	7	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 H?
3. Team G sold as many cups of nuggets as Team J but collected $9 less. How many small cups of nuggets did Team J sell?

(a)
Amount collected by Team F = 100 + 16
= $116

Amount collected by Team G
= 14 x 5 + 9 x 8
= 70 + 72
= $142

Amount collected by Team H
= 7 x 5 + 13 x 8
= 35 + 104
= $139

Team F collected the least money.

(b)
Amount collected by Team H = $139

(c)

	Small cups	Big cups	Total cups	Total amount
Team G	14	9	23	$142
Team J	11	12	23	142 + 9 = $151

Since Team G and Team J sold the same number of cups but Team G collected $9 less, it means that Team J sold more big cups than Team G.

Difference in the total amount collected between Team G and Team J = $9

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

Number of extra big cups sold by Team J
= 9 ÷ 3
= 3

Number of small cups sold by Team J
= 14 - 3
= 11

Answer(s): (a) F; (b) $139; (c) 11
