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
