Given A + E = 100, we have to find A

(1) E = 20% of total tickets, but we don't know the total number of tickets (we cannot assume 100 to be the total tickets sold for the play, as other people apart from Austin and Erica might have sold tickets too). So we cannot find E, thus cannot find A

(2) tickets sold by them = 100 = 25% of total. Thus total tickets for play sold = 400. But this is insufficient to get our answer

Combining, total tickets = 400 and E = 20% of total = 20% of 400 = 80
Thus A = 100-80 = 20. Sufficient!

Hence C answer

If we take total no. of tickets sold as "n", and it is given that A+E=100

1) E = .20(n) , since we dont know the actual no. of tickets sold this option is insufficient.
2) .25 * n = 100, this gives n = 400. Insufficient

Taking both options together we can derive the no. of tickets sold by A.
Answer C
