15Price of each adult ticket in percent = 100%
Price of each child ticket in percent
= 100% - 50%
= 50%
Price of each child ticket
= 50% x 38
=
50100 x 38
= $19
Total sales of tickets
= 152 u + 19 u
= 171 u
171 u = 12312
1 u = 12312 ÷ 171 = 72
Number of tickets sold that were for children
= 1 u
= 1 x 72
= 72
Answer(s): 72
