Final answer:
To find the percentage of tickets that were sold, divide the number of tickets sold by the total number of tickets and multiply by 100. In this case, 40% of the total number of tickets were sold.
Step-by-step explanation:
To find the percentage of tickets that were sold, divide the number of tickets sold by the total number of tickets and multiply by 100. In this case, 120 tickets were sold out of 300 total tickets.
Percentage of tickets sold = (120 / 300) * 100 = 40%
Therefore, 40% of the total number of tickets were sold.
