To find the answer you divide the whole amount of 1456 by 7 since there is the 1 regular priced group and the remaining 6 discounted priced ticked. When you divide the 1456 by 7 it comes out to be 208 and to find the amount of the group of 6 you would multiply the 208 times the 6 and that will give you the amount of the dicount tickets sold. which is 1248.
