But we know that they got the same score, then:



Answer: Each multiple choice question was 5 points

Given:

  • Louann and Carla both got the same score on a test
  • Louann got 14 Multiple Choice Questions correct and scored 24 points for her essay
  • Carla got 16 Multiple Choice Questions correct and scored 14 points for her essay.

To Find: the number of points each multiple choice question was worth.

Solution:

Each multiple choice question was worth 5 points.

Explanation:

Let x denote the number of points each multiple choice question was worth.

Now, Louann's total score can be written as [tex]14x+24[/tex] where the first term is the score on the multiple choice questions and the second term is the score on the essay.

And Carla's score can be written as [tex]16x + 14[/tex] where the first term is the score on the multiple choice questions and the second term is the score on the essay.

As both scores were equal,

[tex]14x+24=16x+14\\16x-14x=24-14\\2x=10\\x=5[/tex]

Therefore, we see that each multiple choice question was for 5 points.
