Answer: 80
Step-by-step explanation:
Let Coleman's test grade be 'x'.
Then according to the given situation, the required equation will be
[tex]\frac{x}{2}+27=67[/tex]
To solve the equation first subtract 27 from both sides, we get
[tex]\Rightarrow\frac{x}{2}=67-27\\\Rightarrow\frac{x}{2}=40[/tex]
Now, multiply 2 on the both sides, we get
[tex]x=80[/tex]
Hence, Coleman's test grade=80
