Write an equation relating the number of questions I get right on a test to the total score I will get if the test has 20 questions each with the same point value and the test is worth 100 points total. I know each question is worth 5 points so I would think that N (number right) =5n (to get the total score) but that is not an equation. What am I forgetting?

Answer 1

5n is correct it would be your score

I guess you could put s=5n

S meaning your total score

Answer 2

Your original equation is correct but if you want to makr if look more complete you can set y equal to your score and put 5n over 100 to show how many points you got right out of 100.
Your equation would look like this
Y=5n/100
