64000-800x+120x\geq 30000
Use the distributive property to multiply 800 by 80-x.
64000-680x\geq 30000
Combine -800x and 120x to get -680x.
-680x\geq 30000-64000
Subtract 64000 from both sides.
-680x\geq -34000
Subtract 64000 from 30000 to get -34000.
x\leq \frac{-34000}{-680}
Divide both sides by -680. Since -680 is negative, the inequality direction is changed.
x\leq 50
Divide -34000 by -680 to get 50.
