Four teams of students sold hot chocolate for charity.
They collected $3 for a small cup of hot chocolate and $6 for a big cup of hot chocolate.

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

	Small cups	Big cups
Team K	19	2
Team L	11	9
Team M	6	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 K?
3. Team N sold as many cups of hot chocolate as Team K but collected $24 more. How many big cups of hot chocolate did Team N sell?

(a)
Amount collected by Team K = 57 + 12
= $69

Amount collected by Team L
= 11 x 3 + 9 x 6
= 33 + 54
= $87

Amount collected by Team M
= 6 x 3 + 10 x 6
= 18 + 60
= $78

Team L collected the most money.

(b)
Amount collected by Team K = $69

(c)

	Small cups	Big cups	Total cups	Total amount
Team K	19	2	21	$69
Team N	11	10	21	69 + 24 = $93

Since Team N and Team K sold the same number of cups but Team K collected $24 more, it means that Team N sold more big cups than Team K.

Difference in the total amount collected between Team N and Team K = $24

Difference in the amount collected for every one extra big cup sold by Team N
= 6 - 3
= $3

Number of extra big cups sold by Team N
= 24 ÷ 3
= 8

Number of big cups sold by Team N
= 2 + 8
= 10

Answer(s): (a) L; (b) $69; (c) 10
