To solve this problem we need to determine if 85% is 34, then what is 100%
The easiest way to do this is to set up a proportion
Being [tex] \frac{34}{85} \frac{x}{100} [/tex]
To figure out the "rule" between 85 and 100, we divide 100 by 85.
100/85 = 20/17
To check our rule we can do 85 x 20/17 which = 100
Now to solve the problem so, 34 x 20/17 = 40
Our answer would be 40 :)
If Marissa got an 85% on her math quiz and she got 34 questions right, there would be a total of 40 questions on the test.
I hope this helps!
