The blues festival sold 30% of tickets at a reduced price $20 and 40% of tickets at $35 and the rest at the door for full price $50. With 10 000 tickets sold, how much did they earn from ticket sales in dollars.

350000$

Step-by-step explanation:

Tey had 10000 tickets.

30% of 10000 is 0,3*10000=3000, so 3000 tickets they sold for 20$, it is 3000*20$=60 000$.

40% of 10000 is 4000 tickets. These tickets they sold for 35$ so it is 4000*35$=140000$.

So, they sold 3000+4000=7000. They had 10000-7000=3000 tickets to sell on the door for 50$.

3000*50$=150000$

They earn:

60000$+140000$+150000$ = 350000$
