70x+4000-50x\leq 4800
Use the distributive property to multiply 50 by 80-x.
20x+4000\leq 4800
Combine 70x and -50x to get 20x.
20x\leq 4800-4000
Subtract 4000 from both sides.
20x\leq 800
Subtract 4000 from 4800 to get 800.
x\leq \frac{800}{20}
Divide both sides by 20. Since 20 is positive, the inequality direction remains the same.
x\leq 40
Divide 800 by 20 to get 40.
