(remember to also consider the extra details emailed to you before the quiz) John's Corporation is building special ChatGPT machines to help students cheat on quizzes and exams. However, he has heard that ChatGPT doesn't condone academic cheating and wants verification on this. As a standard, each cheating machine takes four pounds of steel to build. Steel costs, in theory, $3 per pound. Last month, John's Corporation built 1,000 cheating units, using 3,800 pounds of steel and spending $12,000 on steel purchases. Using the variance terminology discussed in our class (other terminology will give you a zero grade), and nothing that ChatGPT can provide you, honestly calculate and comment on the variances without using ChatGPT (remember to also consider the extra details emailed to you before the quiz).
