Reasoning and Writing Question, what's your interpretation?

In summary, the equation to describe the student's total score as a ratio of total points earned to total points possible is 4n - 1m : 120. This equation accounts for the 4 points earned for each correct answer, the -1 point for each incorrect answer, and the 0 points for each blank answer.

Homework Statement


A student takes a 30-question mathematics exam on which she got n questions correct and m questions incorrect and left k questions blank. If correct answers are worth 4 points, incorrect answers are worth -1 points, and blank answers are worth 0 points, write an equation to describe the student's total score as a ratio of total points earned to total points possible.


Homework Equations


anything you can come up with! it's a logic-based question and they accept many different answers.


The Attempt at a Solution


what I would think, is that since there are 30 question, and if you get them all right you'll get 4 points each, meaning you'll get a 120 if you get a perfect score.
so the equation I came up with is:
4n - 1m + 0k = 120
4n - 1m = 120

any other suggestions? does this answer all parts of the question? looking for clever responses...

Setting it equal to 120 is not a ratio.

Do you have any reason to believe your answer is insufficient?
