Vondaja is selling tickets to a school play. she sells adults tickets for $6 and student tickets for $3. all together she sells 60 tickets and makes $270. how much of each type of ticket does she sell?
a = adult tix value = $ 6 a
s = student tix = 60-a value = $ 3 (60-a) summed = $ 270
6a + 3 (60-a) = 270 solve for 'a' the # adult tix then student tix = 60 - a
