<human>:  Five percent of the 300 senior students got a full merit college scholarship and ten percent of them got a half merit scholarship. How many senior students did not get any scholarships?
<bot>: How many senior students got a full merit scholarship? ** 300 x 5/100 = <<300*5/100=15>>15 senior students got a full merit scholarship.
How many senior students got a half merit scholarship? ** 300 x 10/100 = <<300*10/100=30>>30 senior students got a half merit scholarship.
How many students got scholarships? ** So, a total of 15 + 30 = <<15+30=45>>45 students got scholarships.
How many senior students did not get any scholarships? ** Therefore, 300 - 45 = <<300-45=255>>255 senior students did not get any scholarships.
