Problem: Write an article based on this summary: Subtract the cost of goods sold from the total revenue generated by the goods. Divide the gross profit by the cost of goods sold.

Answer: For example, if you made $200 selling 100 cans of soda and the cost of the goods sold was $100, then your gross profit would be $100. Multiply the number by 100 to get a percentage, rather than a decimal. For example, divide $100 by $100 and the figure is 1. If you multiply it by 100, you get a gross profit percentage of 100 percent.

Problem: Write an article based on this summary: Take a tepid bath. Apply a cold compress. Avoid irritants. Refrain from scratching or rubbing. Avoid exposure to heat. Wear comfortable clothing.

Answer: Both hot and cold temperature extremes can affect hives, and may cause them to worsen when hives are already present. For best results, take a comfortable, room-temperature bath to soothe skin rashes. Sprinkle baking soda, uncooked oatmeal, or finely-ground colloidal oatmeal into your bath to help relieve itching. Avoid using soap until you know whether or not a given soap brand will irritate your hives. Cool, wet compresses can help alleviate the symptoms associated with rashes and hives. Exposure to a cold, wet bandage or dressing can help soothe irritated skin, and may help reduce inflammation by slowing blood flow to the rash. There are many things that can irritate hives and rashes. Even if you are not normally affected by common household irritants, it's best to avoid them until you know how your current rash/hives will react to these items. Common irritants include: Cosmetics Dye (including dye used in clothing) Fur and leather products Hair coloring Latex Nickel products, including jewelry, zippers, buttons, and kitchen utensils Nail care products, including nail polish and artificial nails Soap and household cleaning products Even though your rash may itch very intensely, it's important to avoid scratching or rubbing the rash/hives. Scratching can cause the skin to break, leaving you prone to infection and delaying the healing process. In some people, exposure to heat and humidity can further irritate hives and rashes. If you are experiencing rashes or hives, avoid exposure to heat, humidity, and exercise. If you are experiencing rashes and hives, it's important that you choose the right clothing to prevent further irritating your skin. Choose loose, smooth-textured material like cotton. Avoid constricting clothing and any materials that are rough and scratchy like wool.

Problem: Write an article based on this summary: Get a fire going in a fire pit, fireplace, or grill. Wash the chestnuts and cut an X into each 1. Spread the chestnuts out on a piece of tin foil or a heavy metal pan. Roast the chestnuts over the fire for 20 to 30 minutes. Let the chestnuts cool for 5 minutes and then peel them.

Answer:
You do not need a very large fire, but you will need to have flames and a grill rack positioned just above them to roast chestnuts this way. Place a log into your fireplace, fire pit, or charcoal grill and light it. Use newspaper as kindling to get the fire going. A small amount of lighter fluid may also help to ignite the log. Rinse the chestnuts under warm running water for a minute to clean them. Then, cut an X into the round sides of the chestnuts with a sharp paring knife. Make sure that the X goes through the shell and into the chestnut meat. Cutting an X into the chestnuts is called scoring the chestnuts. Use a large sheet of heavy duty tin foil with several small holes poked into it, a cast iron pan, or a slotted grill pan meant for cooking over an open fire. Position the chestnuts with the X facing up and spread them out in a single layer. If you want to poke holes into a piece of tin foil to roast your chestnuts, use a skewer or small knife and poke a hole in the tin foil about every 1 to 2in (2.5 to 5.1cm). Roast the chestnuts until the shells are blackened, which will take about 20 to 30 minutes depending on the heat of your fire. Put your foil or pan onto a grill rack just above the flames. The flames should be licking the bottom and sides of the foil or pan. Watch the chestnuts closely so you will know when they are done. If possible, keep the fire burning at the same level and avoid getting the fire too hot or the chestnuts may burn. After the chestnut shells are blackened, remove them from the fire, and let them cool before you begin to peel them. Use your fingers to peel away the shells around the scored area of the chestnuts. Make sure to use a fireproof silicone oven mitt to remove the chestnuts from the fire and set the pan onto a potholder or trivet to cool. Place your cooked and peeled chestnuts into an airtight container, and store them in the refrigerator for up to 4 days.
