Answer:
52% of the tickets Nico sold to the movie were adult tickets.
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,
![\textrm{Percentage of adult ticket sold} = \frac{\textrm{Total number of adult ticket sold }}{\textrm{Total number of tickets }} * 100](https://img.qammunity.org/2020/formulas/mathematics/middle-school/6ox9kwr3f9wr25pq24bcsar5hpd1lo8dia.png)
=
![(260)/(500) * 100 = 52](https://img.qammunity.org/2020/formulas/mathematics/middle-school/katyq0y7ciefhk2h1fploxhvi0ewvtt1mq.png)
or, Percentage of adult tickets sold = 52%
Hence, 52% of the tickets Nico sold to the movie were adult tickets.
