Final answer:
The total number of employees (m) when the furniture company has 4 stores (s=4) is found using the equation m = 27 + 21s. Substituting 4 into the equation, we get m = 111.
Step-by-step explanation:
The question relates to a simple linear equation that represents the relationship between the number of stores a furniture company opens and the total number of employees the company will have. To find the total number of employees (m), we need to include both the employees at the corporate headquarters and those at each store. The problem gives us the equation m = 27 + 21s, where s is the number of stores. To find m when s=4, we simply substitute 4 into the equation:
m = 27 + 21(4)
m = 27 + 84
m = 111
Therefore, the total number of employees (m) when there are 4 stores is 111, which corresponds to option C.
