For senior night, the vollyball team sold 850 tickets for the big game and made 6050 dollars. If the presale tickets were 5 dollars and the tickets at the door were 9 dollars, how many tickets were sold at the door?

presale = p

door = d

 

(1) p + d = 850

(2) 5p + 9d = 6050

 

(1) * 5 = 5p +5d = 4250

 

(2)- (1) = 4d = 1800

 

d = 450 tickets
