Quizplus · Accepted Answer

We need to solve the inequality y ≥ 3757:
0.002x - 0.10 ≥ 3757

Adding 0.10 to both sides, we get:

0.002x ≥ 3757.10

Dividing both sides by 0.002, we get:

x ≥ 1,878,550

Rounding up to the nearest whole number, we get:

x = 1,878,551

Therefore, at least 1,878,551 items must be produced to make a profit of at least $3757. Answer choice B is the closest to this value.
