For this challenge exercise you may work with other students in small groups to come up with a common solution, but each team member must upload their own copy of that solution. Make sure you understand how the code works. No freeloading. For online sections you can find team members using the pinned discussion board for Challenge Exercises and then join a group in the People section of the course. (Or communicate using whatever tools you want: Discord, Zoom, Teams, etc.) I want you to write a simple program that asks the user for their age and stores that value in a variable called age. Then use a-branch to offer the user a recommended television series based on their age. You only need two branches. i.e. Two series recommendations. You can divide your recommendations at any age you like and you can make any recommendations you like. You are only being graded on whether or not your program uses a conditional statement to properly branch the flow of your program. I will not mark you down for horrible television recommendations. (My fiancé likes reality television, so if I'm not going to judge her, I won't judge you.) Sample Output Enter age: 23 Try watching Euphoria on HBOmax.

Question 6 (15 points) Marco likes to consume his coffee (C) and biscotti (B) in fixed proportions - he likes exactly 2 biscotti with every cup of coffee. The prices of a cup of coffee and a biscotti are $P_C = 3$ and $P_B = 1$, respectively. Determine Marco's Engel curve for coffee, $C(I)$. In addition, based on the Engel curve, is coffee a normal or inferior good for Marco?

Experiment 1 Procedure Partner: Work with a partner. Place a small amount (about ¼" depth, approximately 1 mL) of Liquid A in a clean, dry, medium-sized test tube and add a similar amount of Liquid B. Shake gently, either side- to-side or with a spanking motion (tapping the side of the test tube with your fingers), and observe the results. Are the liquids miscible or immiscible? Feel free to add a bit more of one or the other of the liquids if this helps to clarify the observation and conclusion. Perform similar testing on the other possible combinations involving liquids A, B, and C, and record the observations in the table below. Observations and Conclusions Test # Liquids Used Miscible/ Immiscible Upper Liquid Lower Liquid Denser Liquid 1 A and B 2 A and C 3 B and C The sequence of liquid densities from highest density to lowest is: Post-Lab Questions 1. Is it possible to tell which of liquid B or C is denser only from the results of Test #3, in which those two liquids are mixed? Explain why this is so. (If it is possible to tell which is denser, present your evidence in a logical sequence that demonstrates how and why.) 2. Is it possible to tell which of liquid B or C is denser by performing only the first two tests above? Explain why this is so. (If it is possible to tell which is denser, present your evidence in a logical sequence that demonstrates how and why.) Chemistry 111-Concepts of Chemistry - Lab Manual 5.1.2 1-3
