Final answer:
When the core industry adds 600 more jobs, the community's total employment will also increase by 600 jobs, making the correct answer C. 600.
Step-by-step explanation:
To determine how many additional jobs will be generated in the community if the core industry adds 600 more jobs, we need to understand the question clearly. If the number of core industry employees increases, it could potentially affect the overall employment numbers in the community. However, based on the information provided, it seems that the question is directly asking by how much the total employment will increase if the core industry adds 600 jobs.
Adding 600 jobs to the core industry simply means the total employment will also increase by that same amount, assuming that no other changes occur in the employment figures elsewhere in the community.
The community's total employment will increase by 600 more jobs, which is the same number that the core industry intends to add. Hence, the correct option in the final answer is C. 600.
