Write an equation that relates 2 variables????

[Guest]

Percent and correct answers:
The percent grade (p) on the exam varies directly with the number (n) of correst answers. (there are 20 question each worth 5 points.) The 2 equations I came up are:

1. n/20=p
0r
2.(5n)(20) =P

Are either of these the right answer?? Mom's gone and dad doesn't even look at Alebra???? Help Please~~~~ :?

1. p=n/20 is the fraction of correct answers. Multiply by 100 if you want a percentage.
