3000x+80000-800x\leq 168000
Use the distributive property to multiply 800 by 100-x.
2200x+80000\leq 168000
Combine 3000x and -800x to get 2200x.
2200x\leq 168000-80000
Subtract 80000 from both sides.
2200x\leq 88000
Subtract 80000 from 168000 to get 88000.
x\leq \frac{88000}{2200}
Divide both sides by 2200. Since 2200 is positive, the inequality direction remains the same.
x\leq 40
Divide 88000 by 2200 to get 40.
