The Blues Festival sold 25% of tickets at a reduced price of $30 and 50% 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?

400,000 in sales

Step-by-step explanation:

50% of 10,000 is 5,000. 5,000x40=200,000

25% of 10,000 is 2,500. 2,500x30=75,000

25% of 10,000 is 2,500. 2,500x50=125,000

add 200,000+75,000+125,000=400,000 in sales

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
