Write a proportion to find how many points xx a student needs to score on a test worth 50 points to get a test score of 78%.

Let
 x = points that a student needs to score on a test
 p = points worth the exam.
 to find how many points to student needs to score on a test to get a test score of 78%. it will be given by
 x = 0.78 * p
 Thus, in a 50-point test, the number of points the student needs to get to get a test score of 78% will be
  x = 0.78 * 50 = 39 points.
