Given that the total worth of jazz concert tickets is $
165
,
000
.
Also, there are a total of
8000
tickets.
Let the number of $
15
tickets be
x
Therefore, the number of $
25
tickets will be
8000
−
x
As, the total amount is $
165
,
000
, we can write that
x
∗
15
+
(
8000
−
x
)
∗
25
=
165
,
000
15
x
+
200
,
000
−
25
x
=
165
,

10
x
=
35
,
000
x
=
3
,
500
Number of $
25
tickets =
8000
−
3
,
500
=
4
,
500
Therefore, there are
