- Which of the three teams collected the most money? Give your answer in letter. (Eg A)
- What was the amount of money collected by Team N?
- Team R sold as many cups of french fries as Team N but collected $18 more. How many big cups of french fries did Team R sell?
(a)
Amount collected by Team N
= 16 x 7 + 4 x 10
= 112 + 40
= $152
Amount collected by Team P
= 14 x 7 + 9 x 10
= 98 + 90
= $188
Amount collected by Team Q
= 7 x 7 + 13 x 10
= 49 + 130
= $179
Team P collected the most money.
(b)
Amount collected by Team N = $152
(c)

Since Team R and Team N sold the same number of cups but Team N collected $18 more, it means that Team R sold more big cups than Team N.
Difference in the total amount collected between Team R and Team N = $18
Difference in the amount collected for every one extra big cup sold by Team R
= 10 - 7
= $3
Number of extra big cups sold by Team R
= 18 ÷ 3
= 6
Number of big cups sold by Team R
= 4 + 6
= 10
Answer(s): (a) P; (b) $152; (c) 10
