Final answer:
The function that can be used to find the number of cookies the baker will have made after x hours is c = 30x + 24.
Step-by-step explanation:
To find the number of cookies the baker will have made after x hours, we can use the equation c = 30x + 24. This equation represents the number of cookies made after x hours. The baker initially made 24 cookies, and then baked 30 more cookies every hour, so we add 30x to represent the additional cookies made after x hours. The constant term, 24, accounts for the initial 24 cookies.
Therefore, the correct function is c = 30x + 24.
