0.05x\geq 65-20
Subtract 20 from both sides.
0.05x\geq 45
Subtract 20 from 65 to get 45.
x\geq \frac{45}{0.05}
Divide both sides by 0.05. Since 0.05 is positive, the inequality direction remains the same.
x\geq \frac{4500}{5}
Expand \frac{45}{0.05} by multiplying both numerator and the denominator by 100.
x\geq 900
Divide 4500 by 5 to get 900.
