50m+8000-40m\leq 8780
Use the distributive property to multiply 40 by 200-m.
10m+8000\leq 8780
Combine 50m and -40m to get 10m.
10m\leq 8780-8000
Subtract 8000 from both sides.
10m\leq 780
Subtract 8000 from 8780 to get 780.
m\leq \frac{780}{10}
Divide both sides by 10. Since 10 is positive, the inequality direction remains the same.
m\leq 78
Divide 780 by 10 to get 78.
