Final answer:

The correct inequality that represents how many hours Amber needs to work to afford a new computer is 6h + 50 ≥ 350. By solving the inequality, we find that Amber needs to work at least 50 hours.

Step-by-step explanation:

To determine how many hours Amber needs to work to earn enough money to buy a new computer, we need to set up an inequality that represents this situation. Amber earns $6 per hour and currently has $50. The cost of the new computer is $350. The inequality that represents the situation is:

6h + 50 ≥ 350.

Let's solve the inequality:

  1. Subtract 50 from both sides to isolate the variable term on one side:
  2. 6h ≥ 300
  3. Divide both sides by 6 to find the number of hours:
  4. h ≥ 50

This means Amber must work at least 50 hours to earn enough money to buy the new computer.
