21 students sleep for 9 hours each night
<em><u>Solution:</u></em>
Given that, Mr.Lee wants to survey 20 of the 210 students in seventh grade about the hours they sleep each night
He finds 2 of the 20 students surveyed sleep for 9 hours each night
Therefore, 2 out of 20 students sleep for 9 hours each night
Find out the percentage of 2 out of 20
Thus 10 % of 210 students sleep for 9 hours each night
Find out 10 % of 210
Thus 21 students sleep for 9 hours each night

Given :
Reserved seat tickets for the football game cost $4.00 each and general admission tickets cost $3.00 each.
After the game is over, the turnstile count shows 1787 people attended the game. The total receipts were $5792.
To Find :
The number of each general admission tickets sold.
Solution :
Let, general admission are x.
So, Reserved seat tickets will be 1787 - x.
Now, total amount T = 3x + 4( 1787 - x )
T = $5792
3x + 4( 1787 - x ) = $5792
-x + 7148 = 5792
x = 1356
Therefore, the number of each general admission tickets sold are 1356.
Hence, this is the required solution.
Seriously: add the x's divide by 2, add the y's divide by 2, bob's your uncle. you have the midpoint.
