Final answer:
The blues festival earned $350,000 from ticket sales.
Step-by-step explanation:
To find out how much the blues festival earned from ticket sales, we need to calculate the revenue from each ticket price category and then add them up.
- Number of tickets sold at $20: 30% of 10,000 = 0.30 * 10,000 = 3,000 tickets
- Number of tickets sold at $35: 40% of 10,000 = 0.40 * 10,000 = 4,000 tickets
- Number of tickets sold at $50: 100% - 30% - 40% = 30% of 10,000 = 0.30 * 10,000 = 3,000 tickets
Total revenue = (Number of tickets sold at $20 * $20) + (Number of tickets sold at $35 * $35) + (Number of tickets sold at $50 * $50)
= (3,000 * $20) + (4,000 * $35) + (3,000 * $50)
= $60,000 + $140,000 + $150,000
= $350,000
