Answer:
Option B. 525 students.
Step-by-step explanation:
The school enrollment for Oakwood Elementary is shown in the graph.
The given graph is representing a linear function. So we will form the function first to calculate the enrollment in 2012.
Equation of the given line in the graph will be in the form of y = mx + c
where m is the slope and c = y- intercept
y-intercept = 300
this line passes through two ordered pairs (0, 300) and (1, 325)
Now the slope m = [tex]\frac{y-y'}{x-x'}[/tex]
m = [tex]\frac{325-300}{1-0}=25[/tex]
Therefore, equation representing the situation will be y = 25x + 300
Now we will put the value of x = year 2012 - year 2003 = 9 years
y = 25×9 + 300
y = 225 + 300
y = 525
Option B. 525 is the correct option.
