Prompt
Calculate gross margin before and after each proposed discount using supplied unit cost, selling price, fees and currency. Input: use only the notes at the end. If a fact this job needs is missing, ask one direct question and do not guess. Format for Discount margin check: 1. Distinguish gross profit from net profit and omit missing calculations. Do not add facts, names, dates, numbers or sources that are not in the notes. Notes: USD. The only fee supplied is a $1.20 card fee per cap. Rent, labour, and ads are absent, so net profit is omitted. Gross profit is price minus unit cost minus that fee. Wool cap. Cost $8.00. Selling price $20.00. Before any discount: gross profit 20.00 - 8.00 - 1.20 = $10.80. Gross margin on price: 54 percent. After 10 percent off, price $18.00: gross profit 18.00 - 8.00 - 1.20 = $8.80. Gross margin 48.9 percent. After 25 percent off, price $15.00: gross profit 15.00 - 8.00 - 1.20 = $5.80. Gross margin 38.7 percent. These are gross figures only.
