0.07x\geq 87.21-10
Subtract 10 from both sides.
0.07x\geq 77.21
Subtract 10 from 87.21 to get 77.21.
x\geq \frac{77.21}{0.07}
Divide both sides by 0.07. Since 0.07 is positive, the inequality direction remains the same.
x\geq \frac{7721}{7}
Expand \frac{77.21}{0.07} by multiplying both numerator and the denominator by 100.
x\geq 1103
Divide 7721 by 7 to get 1103.
