0.28x\leq 1500-600
Subtract 600 from both sides.
0.28x\leq 900
Subtract 600 from 1500 to get 900.
x\leq \frac{900}{0.28}
Divide both sides by 0.28. Since 0.28 is positive, the inequality direction remains the same.
x\leq \frac{90000}{28}
Expand \frac{900}{0.28} by multiplying both numerator and the denominator by 100.
x\leq \frac{22500}{7}
Reduce the fraction \frac{90000}{28} to lowest terms by extracting and canceling out 4.
