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 10
=
70100 x 10
= $7
Total sales of tickets
= 70 u + 21 u
= 91 u
91 u = 6461
1 u = 6461 ÷ 91 = 71
Number of tickets sold that were for adults
= 7 u
= 7 x 71
= 497
