D) $0 < x \leq 497,439$

Quizplus · Accepted Answer

To find the number of items needed for a profit of at least $2487, set y to 2487 and solve for x: $2487 = 0.005x - 0.20$. Adding 0.20 to both sides gives $2487.20 = 0.005x$. Dividing both sides by 0.005 gives $x = 497,440$. Therefore, $x \geq 497,440$ to achieve at least $2487 in profit.
