Answer:
There were 120 questions on the test.
Step-by-step explanation:
It is given that:
Number of questions answered = 54
Grade percent = 45%
Let,
x be the total number of questions
45% of x = 54
[tex]\frac{45}{100}x=54\\0.45x = 54[/tex]
Dividing both sides by 0.45
[tex]\frac{0.45x}{0.45}=\frac{54}{0.45}\\x=120[/tex]
Therefore,
There were 120 questions on the test.
