Answer:each student will sell 9 balloons.
Step-by-step explanation:
The total number of balloons sold by the six groups at the carnival is 162. There are 3 students in each group. This means that the total number of students in the six groups would be 6 × 3 = 18 students.
If each student sells the same number of balloons, then it means that the number of balloons that each student sells will be
162/18 = 9
(x+4) / 44.8 = 35 / 56
56(x+4) = 35(44.8)
56x + 224 = 1568
56x = 1344
x = 24
answer
x = 24 mm
