0.08x = 0.05x + 7.5 Subtract 0.05x from both sides
-0.05x -0.05x
0.03x = 7.5 divide both sides by 0.03
x = 250
at 250 copies its the same price
(note: after 250 the second is cheaper and before 250 the first option is cheaper)
If u have a open circle, then the inequality has no equal sign. But if it is a closed circle, the inequality has an equal sign.
Shading to the left means " less then " .
Shading to the right means " greater then " .
(1) u have an open circle on -7 with shading to the left....
x < -7
(2) u have a closed circle on 4.5 with shading to the left....
x < = 4.5 (thats less then or equal)
(3) u have an open circle on -5 with shading to the right...
x > -5
(4) u have an open circle on 1.5 with shading to the right...
x > 1.5
