50x-12000+100\times 30\times 20\geq 8\times 10^{4}
Use the distributive property to multiply 20 by 2.5x-600.
50x-12000+3000\times 20\geq 8\times 10^{4}
Multiply 100 and 30 to get 3000.
50x-12000+60000\geq 8\times 10^{4}
Multiply 3000 and 20 to get 60000.
50x+48000\geq 8\times 10^{4}
Add -12000 and 60000 to get 48000.
50x+48000\geq 8\times 10000
Calculate 10 to the power of 4 and get 10000.
50x+48000\geq 80000
Multiply 8 and 10000 to get 80000.
50x\geq 80000-48000
Subtract 48000 from both sides.
50x\geq 32000
Subtract 48000 from 80000 to get 32000.
x\geq \frac{32000}{50}
Divide both sides by 50. Since 50 is positive, the inequality direction remains the same.
x\geq 640
Divide 32000 by 50 to get 640.
