Answer:
The room temperature is 25 degrees Celsius.
Step-by-step explanation:
Let the room temperature be [tex]x[/tex], then
[tex]x=100\%[/tex]
From the fact that 100 degrees is 400% the room temperature we get:
[tex]4x=400\%=100[/tex] degrees Celsius.
Therefore,
[tex]x=\frac{100}{4} =25[/tex] degrees Celsius.
Which is the temperature of the room.
