An ad campaign is used to convey an idea or product to an audience. If you decide you have 10,000 dollars to spend on advertising, this is half of the data needed for calculating the CPM. In order to calculate the cost of one thousand impressions, you need the total number of desired impressions (target audience for the ad). For example, a company wants to run a campaign that will get 500,000 impressions. Tools like Google Analytics can be used to determine what kind of traffic a website is getting. Television and print typically use sales or ratings agencies for such data. The cost of the campaign divided by number of desired impressions, multiplied by 1000: (10,000/500,000) x 1000 = 20. This company would be spend 20 dollars per 1000 impressions on their ad campaign with a budget of 10,000 dollars.

Summary: Determine the campaign budget. Determine the total number of impressions. Do the math.

Propane tanks cannot be filled unless they have an overfilling protection device, or OPD. Look at the top of the propane tank to find the valve used to open it. If the valve has a triangular shape or has the letters OPD printed on it, then it's safe to fill. If it doesn't have have a triangular valve, then you cannot fill the tank safely. Some OPDs were made before they were required to have the letters printed on them. Check the label or wrapper on your tank if it has a triangular valve but doesn't have OPD printed on it. Rotate the tank and check for any visual damage, such as dents, bulges, or welds on the surface. If the tank has any damage on the outside, avoid filling it since it's less stable than a new tank. If the tank also has a coat of rust on the outside, don't use it or fill it since it could be unsafe. Cut off the label around the body of the tank and check underneath it for rust or cracks. Standard propane tanks you would use in a gas grill only last for 12 years before they need to be recertified. Look around the collar of the tank, which is the raised round area surrounding the valve, for a listed in MM/YY format. If the tank is older than 12 years, then either replace or have it inspected by a professional propane service. Otherwise, the tank is safe to use. If your tank was recertified, there may be a second date printed on the collar with the letter E next to it. Use the most recent date rather than the first one printed. Get your propane tank recertified 12 years after the first printed date and every 5 years after. The collar of the tank will list the weight of the propane your tank can hold as well as the weight of the empty tank in pounds. Write down both of the numbers so you know how much propane you should add to your tank when you fill it. Propane in typically measured by weight rather than volume.

Summary: Check that the propane tank has a triangular valve. Look for any damage or dents on the outside of the tank. Confirm that the date printed on the tank is less than 12 years ago. Locate the tare weight and amount of propane the tank holds on the collar.

If just a couple of spots on your leather shoes are looking dirty, dampen a soft cloth and rub them gently. Gently rub the detergent over the surface of the shoe with a cloth or a toothbrush, then wipe it clean with a soft, dry rag. Put a few drops of detergent or dish soap in a bowl of warm water and mix it until it's sudsy. Wet a sponge in the solution and wash the surface of the shoe, then rinse the sponge out and wipe clean any residue. Dry the shoe with a soft towel. Spritz some window spray onto a paper towel and rub it gently on the shoe. You can also use a melamine foam, such as a Mr. Clean Magic Eraser, in the same fashion, but avoid doing this too often as the cleaners can dry out the leather. The damp leather will mold to your foot for a good fit. Wear them for about half an hour, or until dry. Water can dry leather out and make it brittle and cracked, so use as little as possible when cleaning your ballet shoes.

Summary: Spot clean with a damp cloth. Rub a drop of regular laundry detergent into the shoe for a deeper clean. Mix detergent or dish soap into a cup of water and apply it to your shoe. Use a window cleaning product to clean your shoe. Put on the shoes after cleaning them. Avoid using much water while cleaning your leather shoes.
