Manufacturing or farming or mining, I think.
Answer:
C. 144 ÷ (70-34)
Explanation:
This answer shows the division sign <em>after </em>144. When the division sign is after a number, that means that the context <em>behind</em> the division sign, which in this case is (70-34), then that means you are <em>dividing by</em> that number (a.k.a. 144).
Also, the difference means the answer when you subtract one number from another number. 70-34 = 36 (a.k.a. the difference.)
Therefore, the correct answer is C. 144 ÷ (70-34).
I hope this helps! :D
