Article: This problem has more than one unknown value, so its equation will have multiple variables. This means you cannot solve for a specific numerical value of a variable. Instead, you will solve to find an equation that describes a variable. Robyn and Billy run a lemonade stand. They are giving all the money that they make to a cat shelter. They will combine their profits from selling lemonade with their tips. They sell cups of lemonade for 75 cents. Their mom and dad have agreed to double whatever amount they receive in tips. Write an equation that describes the amount of money Robyn and Billy will give to the shelter. You are asked to find how much money Robyn and Billy will give to the cat shelter. You know that Robyn and Billy will make money from selling cups of lemonade and from getting tips. You know that they will sell each cup for 75 cents. You also know that their mom and dad will double the amount they make in tips. You don’t know how many cups of lemonade they sell, or how much tip money they get. Since you have three unknowns, you will have three variables. Let x{\displaystyle x} equal the amount of money they will give to the shelter. Let c{\displaystyle c} equal the number of cups they sell. Let t{\displaystyle t} equal the number of dollars they make in tips. Since they will “combine” their profits and tips, you know addition will be involved. Since their mom and dad will “double” their tips, you know you need to multiply their tips by a factor of 2. Since you are writing an equation that describes the amount of money they will give to the shelter, the variable x{\displaystyle x} will be alone on one side of the equation.  Since you are combining their profits and tips, you will be adding two terms. So, x = __ + __. The first term will be equal to their profits. Since they make $0.75 for every cup of lemonade they sell, their profits are equal to .75c{\displaystyle .75c}. So, x=.75c+??{\displaystyle x=.75c\;+\;??}. The second term will be equal to their tips. Since their parents are doubling their tips, their tips will be equal to 2t{\displaystyle 2t}. So, x=.75c+2t{\displaystyle x=.75c+2t}. Since the variable you are describing is already isolated, and all like terms are combined, you have arrived at your final answer. The variable x{\displaystyle x} equals the amount of money Robyn and Billy will donate to the cat shelter. So, the amount they donate can be found by multiplying the number of cups of lemonade they sell by .75, and adding this product to the product of their tip money and 2.
Question: What is a summary of what this article is about?
Solve the following problem. Read the problem carefully and determine what you are asked to find. Summarize what you know, and what you need to know. Assign variables to the unknown quantities. Look for keywords. Write an equation. Interpret your answer.

Problem: Article: If your clothes are particularly loose or sheer and you don’t plan on wearing a bra, choosing nude-colored pasties will be the least conspicuous. If your clothes are slightly see-through or slip out of place, it will be less obvious. These will be thicker and less visible through light fabrics. Paper or fabric pasties often create more visible outlines through thin fabrics than silicone pasties. These are usually available in lingerie shops and large department stores. If you are not worried about the shape of your pasties being visible through your clothing, disposable or fabric pasties are typically cheaper and stay on better than reusable silicone ones. These can often be found in beauty supply shops and clothing stores. If you are buying pasties with sequins or tassels for a costume, be aware that the heavier they are, the stronger the adhesive you use will have to be. If you are buying costume pasties, choose the lightest design you can find. Even if your pasties seem to fit well and stay in place easily, it’s a good idea to wait a few hours and see if the adhesive lasts before wearing them out. If you can move around comfortably after an hour or two without feeling like your pasties have shifted or might be falling off, you can most likely be confident that they’ll stay put when you go out. If your pasties are not staying in place, you may need to try either a different shape of pasties or a different type of adhesive.
Summary: Choose pasties in a nude color for minimal visibility. Use silicone pasties when wearing very sheer fabrics. Use paper or fabric pasties when you don’t need much coverage. Avoid buying very heavy pasties that may fall off. Test your pasties at home before wearing them out for the first time.

Knowing what you’re shooting for will allow you to create an effective diet and exercise plan. If you want to lose 50 lb (23 kg) overall, then 4 lb (1.8 kg) per week would be your goal. However, keep in mind that this is a fast rate of weight loss that is not considered healthy. Ideally, aim for 1–2 lb (0.45–0.91 kg) per week instead, which would still result in a 12–24 lb (5.4–10.9 kg) weight loss over the course of 3 months. to see how many calories you burn in a day. The amount of calories you burn each day depends on your age, height, weight, and the amount of activity you do throughout the day. There are many basal metabolic rate calculators online that you can use to figure out your body’s basic caloric needs. Use one to calculate the amount of calories you are burning on an average day. Once you have figured out what your basic caloric needs are, use this number to help you determine how many calories to cut from your diet. This can also help you set a goal for how many calories to burn with exercise each day. Be realistic with your goal. Don’t drop your caloric intake below 1,200 per day.  For example, if your basal metabolic rate is 2,300, then you could cut your daily caloric intake to 1,300 to work towards a 2 lb (0.91 kg) per week weight loss. To lose 4 lb (1.8 kg) per week, you’d need to burn an extra 1,000 calories per day. This isn’t realistic since it would require you to do around 2 hours of intense cardiovascular exercise every day. Instead, focus on getting 30 minutes of cardiovascular exercise to start and increase the amount and intensity as you get stronger. It’s important to track everything that crosses your lips to get an accurate number for your daily caloric intake. Tracking your exercise in a diary or app can also help you to see how many calories you’re burning in addition to the calories you’ve cut. Make sure to record foods and beverages in the app. This will help to ensure that you’re staying on track with your goals.
