Let the number of student's tickets be x Then the number of gen. adm. tickets, using ONE PART = TOTAL MINUS OTHER PART, is 350-x. Money Money Type Number from from of of EACH ALL ticket tickets ticket tickets ------------------------------------------- student's x $3 $3x gen. adm. 350-x $5 $5(350-x) ------------------------------------------- TOTALS 350 ----- $1450 The equation comes from the column on the right3x + 5(350-x) = 1450 3x + 1750 - 5x = 1450 -2x + 1750 = 1450 -2x = -300 x = 150 = the number of student's tickets. The number of gen. adm. tickets is 350-x or 350-150 or 200 gen. adm.s. Checking: 150 student's is $450 and 200 gen. adm.s is $1000 And indeed $450 + $1000 = $1450 Edwin
