How would you come up with an equation and solve for the following problem?Jenny sold tickets for the annual spring concert at Middletown High...

The cost per ticket for adult =Ca=
3.5

the cost per ticket for student = Cs=
2.5

number of students tickets sold = 4 more than adults
tickets

      s= 4 + a.......
(1)

the total sale = (3.5)a+ (2.5)s =
58.....(2)

sustitute with equatin
(1)

==> (3.5)a + (2.5) (4+a)=
58

==> (3.5)a+ 10+ (2.5)a =
58

==> 6a +10=
58

==> 6a =
48

==> a = 8  ==> s =
12

then she sold 8 adults tickets and 12 students
tickets
