A student needs to earn at least $350 to buy a new tablet. They have already saved $125. If they earn $15 per hour, what is the minimum number of hours they must work to reach their goal?
✓ Correct Answer: Option C
Set up the inequality: 125 + 15h ≥ 350. Subtract 125 from both sides: 15h ≥ 225. Divide by 15 to solve for h, which gives h ≥ 15 hours.
