4800\times 0.47y\geq 40000
Multiply 400 and 12 to get 4800.
2256y\geq 40000
Multiply 4800 and 0.47 to get 2256.
y\geq \frac{40000}{2256}
Divide both sides by 2256. Since 2256 is positive, the inequality direction remains the same.
y\geq \frac{2500}{141}
Reduce the fraction \frac{40000}{2256} to lowest terms by extracting and canceling out 16.
