Answer: 475 referees were surveyed in total.
Step-by-step explanation:
Let x represent the number of referees that were surveyed.
In a recent poll, 32% of the referees who were surveyed said that ejecting angry coaches was their favorite thing to do. This means that the number of referees that gave this response is
32/100 × x = 0.32 × x = 0.32x
If 152 referees gave this response, then the total number of referees that were surveyed would be
0.32x = 152
x = 152/0.32 = 475
