Lenny and Thad spend a certain amount of money from their money box each month to buy comic books. The table shows the relationship between the amount of money (y) remaining in Lenny's money box and the number of months (x):Function 1Number of Months(x) Amount Remaining (in dollars)(y)1 752 603 454 30The equation shows the relationship between the amount of money (y) remaining in Thad's money box and the number of months (x): Function 2: y = −12x + 80 Which statement explains which function shows a greater rate of change? Function 2 shows a greater rate of change, because Lenny spends $15 each month and Thad spends $12 each month. Function 2 shows a greater rate of change, because Lenny spends $75 each month and Thad spends $12 each month. Function 1 shows a greater rate of change, because Lenny spends $15 each month and Thad spends $12 each month. Function 1 shows a greater rate of change, because Lenny spends $15 each month and Thad spends $80 each month.

A baseball coach gives half his players an energy drink to consume before each game; the other half does not receive the energy drink. After a month of games, he analyzes their playing stats. He concludes the energy drink helped improve their performance on the field. How can the coach test the means to be sure his results are not likely to happen by chance? He can pick players at random and analyze their playing stats without calculating means. He can analyze the two groups by calculating the means and the difference of the means. He can pick the players he wants to analyze based on the best stats. He can rerandomize the results by separating the two groups randomly, then calculate the means and the difference of the means.

Renee is going to buy a new car that has a list price of $19,675. She will be responsible for $1,420 in vehicle registration fees, $85 in documentation fees, and 8.92% sales tax. She plans to trade in her current car, a 2002 Buick LeSabre in good condition, and finance the rest of the cost over four years at an interest rate of 11.34%, compounded monthly. If the dealer gives Renee 85% of the listed trade-in value for her car, what will her monthly payment be? Round all dollar values to the nearest cent.

99 POINTSHow much do you share on social media? Do you have accounts linked to your computer, phone, and tablet? The average teen spends around five hours per day online, and checks his or her social media account about 10 times each day. When an image or post is shared publicly, some students are surprised at how quickly their information travels across the Internet. The scary part is that nothing online is really private. All it takes is one friend sharing your photo or updates with the public to create a very public viral trend. For this project you will use what you have learned about exponential functions to study what happens if a social media post is shared publicly. Social Sharing Three Algebra 1 students are comparing how fast their social media posts have spread. Their results are shown in the following table. Student Amber Ben Carter Description Amber shared her photo with 3 people. They continued to share it, so the number of shares increases every day as shown by the function. Ben shared his post with 2 friends. Each of those friends shares with 3 more every day, so the number of shares triples every day. Carter shared his post with 10 friends, who each share with only 2 people each day. Social Media Post Shares f(x) = 3(4)x Day Number of Shares 0 2 1 6 2 18 Carter shared his post with 10 friends, who each share with only 2 people each day. Write an exponential function to represent the spread of Ben's social media post. Write an exponential function to represent the spread of Carter's social media post. Graph each function using at least 3 points for each line. All graphs should be placed together on the same coordinate plane, so be sure to label each line. You may graph your equation by hand on a piece of paper and scan your work or you may use graphing technology. Using the functions for each student, predict how many shares each student's post will have received on Day 3 and then on Day 10. Justify your answers. If Amber decides to mail copies of her photo to the 45 residents of her grandmother's assisted living facility, the new function representing her photo shares is f(x) = 3(4)x + 45. How does this graph compare with the original graph of Amber's photo share? Based on your results, which students' post travels the fastest? How is this shown in the equation form of the functions? If you had to choose, would you prefer a post with fewer friends initially but more shares, like Amber, or more friends initially but fewer shares? Justify your answer with your calculations from previous questions.

A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, determine which system of inequality best explains whether the company can build 10 child bikes and 12 adult bikes in the week. No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100 Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100
