310Price of each adult ticket in percent = 100%
Price of each child ticket in percent
= 100% - 20%
= 80%
Price of each child ticket
= 80% x 20
=
80100 x 20
= $16
Total sales of tickets
= 140 u + 48 u
= 188 u
188 u = 12408
1 u = 12408 ÷ 188 = 66
Number of tickets sold that were for children
= 3 u
= 3 x 66
= 198
Answer(s): 198
