Question

Write a proportion to find how many points x a student needs to score on a test worth 50 points to get a test score of 40%.

Answer 1

Answer:

20 pts

Step-by-step explanation:

 

50 points corresponds to a 100% grade.  How many points (x) correspond to a 40% grade?

     x            40%

------------ = ---------

50 pts       100%

Then 100x = 2000, and so x = 20.

A score of 20 points would correspond with a test score of 40%.
