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
