Answer:
52% of the tickets Nico sold to the movie were adult tickets.
Step-by-step explanation:
At a theater:
Total number of child tickets sold  = 65
Total number of Adult tickets sold  = 260
Total number of Senior tickets sold  = 175
Now,
total number of tickets sold by Nico =  Child tickets  + Adult tickets  + Senior tickets
= 65 + 260 + 175 = 500
So, in total Nico sold 500 tickets at the theater.
Now, [tex]\textrm{Percentage of adult ticket sold} Â = \frac{\textrm{Total number of adult ticket sold }}{\textrm{Total number of tickets }} Â \times 100[/tex]
= [tex]\frac{260}{500} Â \times 100 Â = 52[/tex]
or, Percentage of adult tickets sold  = 52%
Hence, 52% of the tickets Nico sold to the movie were adult tickets.
