250a+6300-210a\leq 5400
Use the distributive property to multiply 210 by 30-a.
40a+6300\leq 5400
Combine 250a and -210a to get 40a.
40a\leq 5400-6300
Subtract 6300 from both sides.
40a\leq -900
Subtract 6300 from 5400 to get -900.
a\leq \frac{-900}{40}
Divide both sides by 40. Since 40 is positive, the inequality direction remains the same.
a\leq -\frac{45}{2}
Reduce the fraction \frac{-900}{40} to lowest terms by extracting and canceling out 20.
