(a)
Let x be the total number of tickets.
x(1-22%-62%) = 2688
x(16%) = 2688
x = 2688/16%
x = 16800
The total number of tickets is 16800.
(b)
Number of $200 tickets = 2688
Number of $400 tickets
=16800*62%
=10416
Total number of $200 and $400 tickets
=2688+10416
=13104
Let x be the total number of tickets.
x(1-22%-62%) = 2688
x(16%) = 2688
x = 2688/16%
x = 16800
The total number of tickets is 16800.
(b)
Number of $200 tickets = 2688
Number of $400 tickets
=16800*62%
=10416
Total number of $200 and $400 tickets
=2688+10416
=13104
