30% =
30100 =
310Price of each adult ticket in percent = 100%
Price of each child ticket in percent
= 100% - 30%
= 70%
Price of each child ticket
= 70% x 30
=
70100 x 30
= $21
Total sales of tickets
= 210 u + 63 u
= 273 u
273 u = 17199
1 u = 17199 ÷ 273 = 63
Number of tickets sold that were for children
= 3 u
= 3 x 63
= 189
Answer(s): 189
