AI Thread Summary
An 8 lbs. roast beef costs $2.79 per pound, totaling $22.32. However, only 65% of the roast is edible, meaning the actual usable portion is 5.2 lbs. To determine the effective cost per pound of the edible portion, divide the total price by the edible weight. This results in an adjusted price of approximately $4.28 per pound for the edible roast beef. Understanding the edible yield is crucial for accurate cost assessment.
