Chris and her dad are planning a trip to a game for four people. He asked her to determine how much it will cost for their tickets and snacks at the game. Chris’s dad thinks they may go to several games this year.They chose the section of the park where they wanted to sit, and Chris found the prices for seats in that section. She found three ways to buy the tickets.Individual game tickets for the section they chose are $30 per ticket.The cost of a 21-game package of tickets for one seat in their section is $20 per game.A package of 10 tickets costs $200, and they can be used in any combination of single tickets per game or multiple tickets per game in their section.Chris thinks they will each want a hot dog and a soft drink, and two people can share a bag of peanuts. This table shows the cost of those items at the game.FOOD COSTSFood ItemCostHot dog$6.00Soft drink$4.50Peanuts$5.00An additional cost will be the $20 charge at the parking lot.1.Read "Going to a Baseball Game" and answer the question.The people who attended the second game purchased h hot dogs, d?soft drinks, and 2 bags of peanuts.?They spent a total of $61 on food.Which equation represents the cost spent on food?/files/assess_files/310cb8f0-00c8-4555-937e-3e4f294d213e/formula_sheets/FL-IBTP_Math_Reference_Sheet_Grade_9-12.pdfFL-IBTP_Math_Reference_Sheet_Grade_9-12.pdf?A.?B.?C.?D.??Read the following and answer the questions below:Pollution Research Pollution Research In her environmental science class, Kaylie has been learning about air pollution. The teacher told the class that pollution occurs when chemicals and particles are released into the air we breathe. These pollutants can be very harmful to people and other living organisms in the environment.Several natural processes release pollutants. Most pollution is caused by human activities that release hazardous chemicals into the air through their exhaust: when cars run and burn gasoline, when factories use coal for fuel, or even when gas stoves are used to cook food. These chemicals, when exposed to sunlight, can react with other substances to form smog, which is the haze that is often seen surrounding large cities. Air pollution and smog are harmful to people’s health and to the environment. They have been known to aggravate asthma and respiratory disease as well as to cause acid rain.Kaylie is interested in learning more about what causes air pollution and what she can do to minimize it. She has noticed that the city she lives in has areas with more smog than others. She would like to know what chemicals are present in the air in this city. She goes to the local climate research center to get more information.At the research center, scientists inform Kaylie that the main source of pollution in the area is car exhaust from commuters traveling in and out of the city every day. Car exhaust produces a chemical known as nitrogen dioxide that can absorb light and eventually create pollutants. The scientists tell Kaylie that when nitrogen dioxide breaks down, it forms particles of oxygen that are different from the oxygen we breathe. These oxygen particles combine with other substances in the air to form pollutants. Kaylie realizes that when the nitrogen dioxide from car exhaust breaks down and decreases in amount, this means that oxygen particles, and therefore pollutants, are being formed and are increasing in amount.The scientists at the research center have been doing pollution experiments in their laboratories. They have been comparing the amount of nitrogen dioxide that breaks down with the amount of oxygen particles formed. They do this by measuring the concentrations of these substances over short periods to see how they change. Concentrations are determined by finding the amount of a substance per unit volume. In this case, the scientists measured concentration in micrograms per cubic meter They let Kaylie look at the results from a recent investigation.??These results show how the concentration of nitrogen dioxide and oxygen particles changed in relation to one another over a period of 20 minutes. After looking at the results, Kaylie is convinced that nitrogen dioxide is harmful to the environment. She will remember her trip to the research center the next time she needs to go somewhere. Maybe she will try walking or riding her bike more often!? ?* Micrograms are very small units that are a fraction of a gram, so 2.Read "Pollution Research" and answer the question.Kaylie’s classmates do a pollution experiment in which they measure growth of the same type of plant over the course of?three weeks?in two different areas. Area 1 has a high concentration of nitrogen dioxide. Area 2 has a low concentration of nitrogen dioxide.
