Markup and markdown calculations are used to determine the selling price of a product based on its cost. The markup is the amount added to the cost to determine the selling price, while the markdown is the amount subtracted from the selling price to determine the sale price. The markup percentage is calculated by dividing the difference between the selling price and the cost by the cost, and then multiplying by 100. The markdown percentage is calculated by dividing the difference between the selling price and the sale price by the selling price, and then multiplying by 100. These calculations help businesses set prices that will cover costs and generate profit. **

Gross margin is the difference between the selling price of a product and the cost of goods sold, expressed as a percentage of the selling price. It represents the profit a company makes on each unit sold. On the other hand, gross markdown is the difference between the original selling price of a product and the reduced selling price, expressed as a percentage of the original selling price. It represents the reduction in price made to stimulate sales or clear out inventory. In summary, gross margin measures profitability, while gross markdown measures the extent of price reduction. **

No, the organic eggs from the supermarket are not fertilized. Organic eggs come from hens that are raised in organic, free-range environments and are not in contact with roosters. Therefore, the eggs laid by these hens are not fertilized and will not develop into chicks. The hens lay eggs regardless of whether they have been in contact with a rooster, so the eggs sold in supermarkets are not fertilized. **

Cashiers at supermarkets typically do not pack groceries because their primary responsibility is to scan and process the items being purchased. Packing groceries is usually the responsibility of the customer, as it allows them to organize their items according to their preferences and needs. Additionally, having customers pack their own groceries helps to expedite the checkout process and allows the cashier to focus on efficiently processing transactions. Some supermarkets may offer bagging services, but this is often a separate role from the cashier. **
