- Which of the three teams collected the least money? Give your answer in letter. (Eg A)
- What was the amount of money collected by Team P?
- Team N sold as many cups of coke as Team Q but collected $8 less. How many small cups of coke did Team Q sell?
(a)
Amount collected by Team M
= 17 x 4 + 2 x 6
= 68 + 12
= $80
Amount collected by Team N
= 13 x 4 + 7 x 6
= 52 + 42
= $94
Amount collected by Team P
= 6 x 4 + 10 x 6
= 24 + 60
= $84
Team M collected the least money.
(b)
Amount collected by Team P = $84
(c)

Since Team N and Team Q sold the same number of cups but Team N collected $8 less, it means that Team Q sold more big cups than Team N.
Difference in the total amount collected between Team N and Team Q = $8
Difference in the amount collected for every one extra big cup sold by Team Q
= 6 - 4
= $2
Number of extra big cups sold by Team Q
= 8 ÷ 2
= 4
Number of small cups sold by Team Q
= 13 - 4
= 9
Answer(s): (a) M; (b) $84; (c) 9
