To solve the inequality 10w + 213 ≥ 299, we can subtract 213 from both sides to isolate the term with the variable:

10w + 213 - 213 ≥ 299 - 213
10w ≥ 86

Next, divide both sides of the inequality by 10:

10w/10 ≥ 86/10
w ≥ 8.6

Therefore, the correct solution is w ≥ 8.6, or "w greater than or equal to 8.6."
