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?
5P + 9D = 6050 (eq 1)
P + D = 850 multiply both sides of this times 5
5P + 5D = 4250 (eq 2)
subtract (eq 2) from (eq 1)
5P + 9D = 6050
5P + 5D = 4250
4D = 1800
D = 450 at the door
substitute 450 back into either equation ... pick (eq2, it's easier)
P + 450 = 850
P = 850 – 450
P = 400 presale
