You can put this solution on YOUR website!
Since you wnt to know your percent for the right ones (let the percent for correct ones be x)
First:42-14=30
next 42 correct means 100 percent
30 correct we need to find the percent.
42--------100
30--------x
So cross multiply:
42x=30+x+100
x=30+x+100%2F42
71.43
Your percent is 71.43%
