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%.
i still dont understand
To find the number of points, x, that a student needs to score on a test worth 50 points to get a test score of 40%, you can set up a proportion.
Let's assume that the student's score is represented by x.
Given that the test is worth 50 points and the desired percentage score is 40%, we know that:
x / 50 = 40 / 100
To solve this proportion, cross-multiply:
100x = 40 * 50
Simplifying further:
100x = 2000
Now, divide both sides of the equation by 100 to isolate x:
x = 2000 / 100
x = 20
Therefore, the student needs to score 20 points on the test worth 50 points to achieve a test score of 40%.
