Answer:82.5% of the attendees will not buy popcorn
Explanation:
At a future showing of the movie 23 jump street-men in black,28 of the 160 attendees will buy popcorn. This means that the percentage of attendees that will buy popcorn is
28/160 × 100 = 0.175 × 100 = 17.5%.
Since the total number of attendees is expressed as 100%, it means that the percentage of attendees that will not buy popcorn would be
100 - 17.5 = 82.5%
