Answer: 5 levels

Step-by-step explanation:

      We will set up a system of equations and solve. Let x be the number of levels beaten, and let y be the number of total points.

          Miguel's version:

              y = 1x + 25

          Lauren's version:

              y = 2x + 20

      Now, we will graph both equations. The x-coordinate of the point-of-intersection is the answer to our question.

          See attached.

             The lines intersect at (5, 30) meaning they will have the same number of points after 5 levels, with 30 points.
