If all 10,000 tickets are sold, we get:BTGmoderatorDC wrote:Tickets for all but 100 seats in a 10,000-seat stadium were sold. Of the tickets sold, 20% were sold at half price and the remaining tickets were sold at the full price of $2. What was the total revenue from ticket sales?

D. $19,800
E. $21,780
20% sold for $1 each = 2000*1 = 2,000
80% sold for $2 each = 8000*2 = 16,000
Total revenue = 2000+16000 = 18,000
Since 100 tickets are not actually sold, the total revenue must be a bit less than 18,000.
The correct answer is B.

We see that 10,000 - 100 = 9,900 tickets were actually sold.BTGmoderatorDC wrote:Tickets for all but 100 seats in a 10,000-seat stadium were sold.

0.2 x 9,900 = 1,980 tickets were sold for 1 dollar each, so these tickets generated 1,980 dollars in revenue.
9,900 - 1,980 = 7,920 were sold for 2 dollars each, so these tickets generated 15,840 dollars in revenue.
The total revenue earned was 1,980 + 15,840= 17,820 dollars.
