2 x 15 = 30, 9 x 22 = 198, 198 + 30 = 228.
So the answer is A 2 children, 9 adults.

Answer:
Hence, the model that best represents the data is:

Step-by-step explanation:
We are given a table that  shows the estimated number of lines of code written by computer programmers per hour when x people are working. 
We are asked to find which model best represents the data?
So for finding this we will put the value of x in each of the functions and check which hold true that which gives the value of y i.e. f(x) as is given in the table:
We are given 4 functions as:
A)

B)

C)

D)

We make the table of these values at different values of x.
x                  A                 B                C               D
2              66.66          49.3            52.5           50
4             94.57            71.44           106.3         104  
6             134.14           103.57         160.1          158
8             190.27          150.14          213.9         212
10           269.91           217.64         267.7         266
12           382.85          315.5           321.5          320.
Hence, the function that best represents the data is:
Option C.
y=26.9x-1.3
