A theater sells adult tickets for $11 and child tickets for $6. At one show, the theater sold 180 tickets and received $1740.
How many adult tickets were sold? Enter the answer in the box.
Make a system of equation A = adult, C = child Total tickets = 180 Total cost = $1740 A + C = 180 11A + 6C = 1740 Use any method I will use elimination (A + C = 180) * 6 6A + 6C = 1080 11A + 6C = 1740 Subtract both sides -5A = -660, A = 132
