100a+600-60a\leq 800
Use the distributive property to multiply 60 by 10-a.
40a+600\leq 800
Combine 100a and -60a to get 40a.
40a\leq 800-600
Subtract 600 from both sides.
40a\leq 200
Subtract 600 from 800 to get 200.
a\leq \frac{200}{40}
Divide both sides by 40. Since 40 is positive, the inequality direction remains the same.
a\leq 5
Divide 200 by 40 to get 5.
