Louann got 14 multiple choice questions correct and 24 points for her essay, so:
Carla got 16 multiple choice questions correct and 14 points for her essay, so:
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.
