The answer is 2:50. 2 people didnt dress out, & there are 50 total students.
Supplementary angles have a sum of 180 degrees.
If one angle is x, its supplementary angle is 180-x.
We are told that x is 8 less than triple its supplements so:
x=3(180-x)-8
x=540-3x-8
4x=532
x=133
The answer would be 30% , 3% would only be correct if he gave 0.3/10
