Challenger Elementary School has 800 students. Every Wednesday, 12 percent of the students stay after school for Chess Club.

DENIUS [597]

Let's set up a proportion.

$\frac{x}{800} \frac{12}{100}$

Then solve for x:
12 x 800 = 9600
9600/100 = 96

96 is 12% of the 800 students. :)

Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)

Inessa05 [86]

2 times 2=4
multiply first equation by 2 to get
-4x+6y=12
then add to get

-4x+6y=12
<u>4x-2y=8 +</u>
0x+4y=20

4y=20
y=5

sub back
-2x+3y=6
-2x+3(5)=6
