The Blues Festival sold 20% of tickets at a reduced price of $30 and 30% of tickets at $40 and the rest at the door for full price of $50. With 10,000 tickets sold, how much did they earn from ticket sales in dollars?

$430,000

Step-by-step explanation:

20% of 10,000 = 2000

therefore, 2000 x $30 = $60,000

30% of 10,000 = 3000

therefore, 3000 x $40 = $120,000

50% of 10,000 = 5000

therefore, 5000 x $50 = $250,000

add all dollar amounts together to get $430,000

12= 9x

divide by 9

12/9 =
