Adult tickets for the school musical sold for 3.50 and student tickets sold for 2.50. Three hundred twenty-one tickets were sold all together for 937.50. How many of each kind of ticket were sold?

a = # adult tix                               value =   $  3.50 a

s = # student tix =   321-a            value = $   2.50 ( 321 -a)

                                summed = 937.5

 

3.5 a   + 2.5(321-a) = 937.5                  solve for 'a' the adult tix sold             then student tix = 321-a
