If a market hog sells for $100, how much check-off money would the producer have to pay to the National Pork Board?

To determine the amount of check-off money a producer would pay to the National Pork Board when selling a market hog for $100, it is necessary to understand the current check-off rate, which is set at 0.40%. This means that for every $100 sale, the producer is required to pay 40 cents as check-off money to support programs for research, promotion, and education within the pork industry.

Thus, if a market hog sells for $100, the check-off fee would indeed be 40 cents. This amount is collected uniformly from producers and is crucial for funding initiatives that benefit the entire pork industry, making it the correct answer.
