Article: They come in several sizes and wingless and flightless as well.  Flightless is a better choice than wingless, as wingless can revert back to the flying.  You shouldn't have to worry about escapees, because the company will have secured them. They breed in the vials, but it's not recommended: they will over-crowed and die. Fill the cup up 1/4 full, maybe a little more, and this lasts about a month or so. If you use "Organix" remember to add the mold inhibitor.
Question: What is a summary of what this article is about?
When buying fruit flies, choose the type of fruit fly you want, online. When buying them, get an extra order of fruit fly media (food), bedding and culture cups. When the box comes, remove the contents. If they are in small vials, put them in a freezer for a couple seconds, no more than ten, to slow them down a little, then pour them into a culture cup. Pour the fly food into a culture cup, adding the amount of water the package instructs you to. After assembling your culture cup, add the flies you bought/caught.

Problem: Article: In order to calculate interest paid on a mortgage loan, we will calculate the monthly payment and then use the simple method from method 1 above to calculate interest. The monthly payment equation can be represented as follows: M=Pr(1+r)n(1+r)n−1{\displaystyle M=P{\frac {r(1+r)^{n}}{(1+r)^{n}-1}}}. These variables represent the following inputs:  M is your monthly payment. P is your principal. r is your monthly interest rate, calculated by dividing your annual interest rate by 12. n is your number of payments (the number of months you will be paying the loan) You will need to input your principal, monthly interest rate, and number of payments in order to find your monthly payment. This information can be easily found in your loan agreement or from a quoted loan estimate. Check the information again to be sure of its accuracy before using it in calculations.  For example, imagine you have a $100,000 mortgage loan with 6 percent annual interest over 15 years. Your input for "P" would be $100,000. For "r," you would use your monthly interest rate, which would be 0.06 (6 percent) divided by 12, or 0.005 (0.5 percent). For "n" you would use your total number of payments, one for each month in fifteen years, which would be 12*15, or 180. In this example, your complete equation would look like this:M=$100,0000.005(1+0.005)180(1+0.005)180−1{\displaystyle M=\$100,000{\frac {0.005(1+0.005)^{180}}{(1+0.005)^{180}-1}}} " Simplify your terms by doing the first step in the order of operations, which is adding the 1 and "r" inside the parentheses on the top and bottom of the equation. This is a simple step that will make your equation look much less complicated. After this step, your sample equation would look like this:M=$100,0000.005(1.005)180(1.005)180−1{\displaystyle M=\$100,000{\frac {0.005(1.005)^{180}}{(1.005)^{180}-1}}} The result of the previous step must now be raised to the power of "n." Keep in mind that only the figures inside the parentheses will be raised to this power, not the "r" outside of it or the -1 at the end. After this step the sample equation would look like this:M=$100,0000.005(2.454)2.454−1{\displaystyle M=\$100,000{\frac {0.005(2.454)}{2.454-1}}} Here, you should multiple "r" times the result of the last step on the top (the numerator) and subtract 1 from your result on the bottom (the denominator). The same equation would look like this after this step:M=$100,0000.012271.454{\displaystyle M=\$100,000{\frac {0.01227}{1.454}}} In the example, your equation would now be:M=$100,000∗(0.008439){\displaystyle M=\$100,000*(0.008439)} This will give you your monthly loan payment. In the example, this would be ($100,000)*(0.008439), or $843.90. This represents your monthly payments. With this information, you can now calculate total interest paid and interest paid each month. Both will allow you to compare different amounts of interest you might pay with different loans and see which one is right for you.  Find monthly interest paid by dividing "P" by "n" and subtracting this number for your monthly payments, "M." Find total interest paid by multiplying your monthly payment "M" by "n" and then subtracting "P."
Summary: Understand the equation. Input your information into the equation. Simplify your equation by adding 1 to the "r. Solve the exponents. Simplify again. Divide the numerator by the denominator. Multiply "P" by this result. Calculate interest paid using the payment information.

Sometimes you can't put a physical barrier up to keep your cat out of a room. In this case, you will need to make the room uncomfortable for it to be in. Make loud noises whenever it enters the room or shoo it away. Note that if you do this, the cat may associate the noise with you and start to avoid you.  You can even employ stronger methods in some cases. For example, spill a small amount of water on the floor of your bathroom if you don't want your cat in there. A cat may hate to get its feet wet on any excess water on the floor. Another example is to make sure the cat has nowhere to hide in a room. Sometimes a cat likes going under beds or in corners to feel safe. With this type of cat you can block off access to under the bed or any other hiding spaces. This will make your cat uncomfortable in the room. Every time it goes near the room, have a spray bottle ready to spray a little water at it. This will make sure it knows that its actions are unacceptable. However, only use this method if you are prepared to accept damaging your relationship with the cat. It is highly likely the cat will associate the water spray with you, the sprayer, rather than the room. Thus, the cat is more likely to flee and not want to spend time in your company. You simply place the device in the doorway to the room and let it deter your cat from the area. Put a small amount of vinegar at the room's entrance or in areas of the room. This usually helps, as most cats hate the odor of vinegar. This advice is anecdotal, however, as some people find it helps while for others it makes no difference. Alternatively, fill a spray bottle halfway with vinegar. Fill the other half with lime or lemon juice. Spray at the entrance to the room and on beds and other places the cat usually goes. This will deter many cats from scratching on furniture or spending time in the room. If you go this route, the vinegar spray needs fairly constant reapplication. Make a different room more comfortable for the cat. Make another room cat-appealing so the cat will go there instead. Offer the cat several nice sleeping places (although it's likely to chose its own) including a high perch. Provide food, water, and a litter tray, as well as toys. This involves making a big fuss of the cat and making being in the room you want it to be in a pleasant experience. The goal is to make sure your cat associates the room with good things and wishes to return there. You may want to scatter extra tasty treats around the room so that it seems a more appealing place.
