Answer:
C. [tex]12<x<25[/tex]
Step-by-step explanation:
The function t, where [tex]t(x) = 9.50 x[/tex] represents the amount of money Fernando earns given the number of hours, x, he works.
The domain of the function [tex]t(x)[/tex] are all possible values for x.
It is known that Fernando works between 12 and 25 hours each week, so the number of hours, x, he works satisfies the inequality
[tex]12<x<25[/tex]
