Answer:
19 people were surveyed
Step-by-step explanation:
0 children = 3
1 child = 4
2 children = 5
3 children = 5
4 children = 2
3 + 4 = 7 + 10 = 17 + 2 = 19
So every 5 inches in height, there are 32 marbles. You want to know how many marbles there are per 18 inches in height.

To get from 5 to 18, you multiply by 3.6.
Do the same thing to the numerator; 32 × 3.6 = 115.2.
Since 0.2 marbles is no marbles, you round down.
There are 115 marbles in the box.
