Answer:
80%
Explanation:
To find the percentage sold to sixth graders, take the number sold to sixth graders over the total
percentage to sixth graders = tickets sold to sixth graders/ total tickets
The total tickets are 300
Tickets to sixth graders is 240
Substitute it in
percentage to sixth graders = 240/300
=24/30
=4/5
=.8
Multiply this by 100 to give the percent
80%
