Answer:   23.  see attached   25.  no question content (see below)   26.  A. Ken made a mistake between steps 1 and 2Step-by-step explanation:23. Profit is the difference between revenue and cost. The glee club will have revenue of $2 for each cupcake sold. We can let x represent the number of cupcakes sold, so 2x will be their revenue.The glee club has costs of $20 for booth rental. Then their profit (y) is ...   y = 2x -20 . . . . . . difference between revenue and costYou recognize the form of this equation as being "slope-intercept" form, so you know you can graph the point (0, -20) as the y-intercept and make the line have an upward slope of 2 units rise for each 1 unit of run.The graph is attached. (Don't forget to label the axes.)__25. There is no question here. We observe that Aaron made a mistake in application of the distributive property when he wrote Line 3. The rest of the solution should be ...   4x -4 = 15   4x = 19   x = 19/4 = 4.75__26. Ken made the same mistake: misapplication of the distributive property. His line 2 should have been ...   line 2: 10y -2 = 18   line 3: 10y = 20   line 4: y = 2Ken made a mistake between steps 1 and 2.
