Answer:

23. see attached

25. no question content (see below)

26. A. Ken made a mistake between steps 1 and 2

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 cost

You 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 = 2

Ken made a mistake between steps 1 and 2.
