A) $\{ x \mid 0 < x \leq 254,539 \}$
B) $\{ x \mid x \geq 254,540 \}$
C) $\{ x \mid x \geq 254,660 \}$
D) $\{ x \mid x \geq 253,540 \}$

Quizplus · Accepted Answer

We need to solve the inequality:
$$0.005x+0.30\geq 1273$$
Subtracting $0.30$ from both sides gives us:
$$0.005x\geq 1272.70$$
Dividing both sides by $0.005$:
$$x\geq 254,540$$
Therefore, the solution set is $\{ x \mid x \geq 254,540 \}$, which corresponds to choice $\boxed{	extbf{(B)}}$.
