- 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 G?
- Team F sold as many cups of ice cream as Team H but collected $8 less. How many small cups of ice cream did Team H sell?
(a)
Amount collected by Team E
= 16 x 5 + 5 x 7
= 80 + 35
= $115
Amount collected by Team F
= 14 x 5 + 9 x 7
= 70 + 63
= $133
Amount collected by Team G
= 7 x 5 + 12 x 7
= 35 + 84
= $119
Team E collected the least money.
(b)
Amount collected by Team G = $119
(c)

133 + 8 = $141 |
Since Team F and Team H sold the same number of cups but Team F collected $8 less, it means that Team H sold more big cups than Team F.
Difference in the total amount collected between Team F and Team H = $8
Difference in the amount collected for every one extra big cup sold by Team H
= 7 - 5
= $2
Number of extra big cups sold by Team H
= 8 ÷ 2
= 4
Number of small cups sold by Team H
= 14 - 4
= 10
Answer(s): (a) E; (b) $119; (c) 10
