One of the easier ways to graph this line is the intercept method:
First, let x=0. Then 2y=8, and y=4. The y-intercept is (0,4).
Next, let y = 0. Then 4x = 8. The x-intercept is (8,0).
Plot these 2 points. Then draw a straight line through them.
The Answer would be x=72. Why? Because

is your %. You Cross multiply 240 * 30 = 100x
240 time 30 = 7200. you want x to be alone so you do 7200 divided by 100 equaling 72. So you get x=72.
