Four teams of students sold nuggets for charity.
They collected $7 for a small cup of nuggets and $10 for a big cup of nuggets.

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

	Small cups	Big cups
Team D	17	3
Team E	14	8
Team F	8	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 F?
3. Team E sold as many cups of nuggets as Team G but collected $21 less. How many small cups of nuggets did Team G sell?

(a)
Amount collected by Team D = 119 + 30
= $149

Amount collected by Team E
= 14 x 7 + 8 x 10
= 98 + 80
= $178

Amount collected by Team F
= 8 x 7 + 12 x 10
= 56 + 120
= $176

Team D collected the least money.

(b)
Amount collected by Team F = $176

(c)

	Small cups	Big cups	Total cups	Total amount
Team E	14	8	22	$178
Team G	7	15	22	178 + 21 = $199

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

Difference in the total amount collected between Team E and Team G = $21

Difference in the amount collected for every one extra big cup sold by Team G
= 10 - 7
= $3

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

Number of small cups sold by Team G
= 14 - 7
= 7

Answer(s): (a) D; (b) $176; (c) 7
