Answer:

2 students failed

Step-by-step explanation:

Lets say the variable y is the number of students who failed.

And to find the percentage of students who failed you subtract 95% from 100%:

[tex]100 - 95 = 5[/tex]

So, then the equation is:

[tex] \frac{5}{100} = \frac{y}{40} [/tex]

Simplify:

[tex]100y = 200[/tex]

Divide 100 from both sides:

[tex]100 \div 100y = 200 \div 100[/tex]

Simplify:

y=2
