- 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 J?
- Team M sold as many cups of french fries as Team J but collected $18 more. How many big cups of french fries did Team M sell?
(a)
Amount collected by Team J
= 17 x 4 + 3 x 7
= 68 + 21
= $89
Amount collected by Team K
= 12 x 4 + 7 x 7
= 48 + 49
= $97
Amount collected by Team L
= 6 x 4 + 10 x 7
= 24 + 70
= $94
Team K collected the most money.
(b)
Amount collected by Team J = $89
(c)

89 + 18 = $107 |
Since Team M and Team J sold the same number of cups but Team J collected $18 more, it means that Team M sold more big cups than Team J.
Difference in the total amount collected between Team M and Team J = $18
Difference in the amount collected for every one extra big cup sold by Team M
= 7 - 4
= $3
Number of extra big cups sold by Team M
= 18 ÷ 3
= 6
Number of big cups sold by Team M
= 3 + 6
= 9
Answer(s): (a) K; (b) $89; (c) 9
