A. C = 3,000 + 2,500x
B. C = 12(3,000 + 2,500x)
C. C = 10(3,000) + 2,600x
D. C = 4,000 + 12(2,700x)
🧠 Explanation (Math):
Given: Monthly fixed $3000 and salary $2500 per employee; $x$ employees for 12 months Step 1: Monthly cost $=3000+2500x$. Step 2: Yearly cost $=12(3000+2500x)$. Final Answer: $C=12(3000+2500x)$
