A community theater troupe sold 1200 tickets for a performance. One third of those tickets were adult tickets and the rest were children's tickets. 60% of all children's tickets were used, along with 120 adult tickets. What percentage of all tickets were not used for the performance?

A. 48%

B. 50%

C. 56%

D. 60%

E. 64%

Adult Tickets = 1200/3 = 400

Children Tickets = 1200-400 = 800

Children Tickets used = 800 × 0.6 = 480

Adult Tickets used = 120

Total used tickets = 480 + 120 = 600

So 600/1200 = 0.5

So 50%
