The school band sold 150 tickets to their concert. If 90 of the tickets were adult tickets,

what percent of the tickets sold were adult tickets?

To find the percentage of adult tickets sold, we need to divide the number of adult tickets by the total number of tickets sold and then multiply by 100.

Percentage of adult tickets = (90 / 150) * 100
Percentage of adult tickets = 0.6 * 100
Percentage of adult tickets = 60%

Therefore, 60% of the tickets sold were adult tickets.
