It is an AP
a=1
d=1
Sn=$100= 10000 cents
Sn=n/2[2a+(n-1)d]
10000=n/2[2+n-1]
20000=n^2+n
n^2+n-20000=0
Find the roots of the equation by quadratic formula

a= 1 , b= 1 , c= -20000

b^2-4ac= 1 + 80000
b^2-4ac= 80001

x1=( -1 + 282.84 )/ 2
x1= 140.92

x2=( -1 -282.84 ) / 2
x2= -141.92
Ignore negative value Minimum tickets to be sold = 141 tickets
