Answer:
The average number of people per car is 2.91
Step-by-step explanation:
To find the average number of people per car, we divide the total number of people by the total number of cars.
We have that:
57 cars had 4 people
61 cars had 2 people
9 cars had 1 person,
5 cars had 5 people.
Number of people:
57*4 + 61*2 + 9*1 + 5*5 = 384
Number of cars:
57 + 61 + 9 + 5 = 132
Average:
384/132 = 2.91
The average number of people per car is 2.91
