To solve the inequality 10w + 213 ≥ 299, you need to isolate the variable w.
Subtract 213 from both sides of the inequality:
10w + 213 - 213 ≥ 299 - 213
10w ≥ 86
Next, divide both sides of the inequality by 10 to solve for w:
10w/10 ≥ 86/10
w ≥ 8.6
Therefore, the correct answer is A. w ≥ 8.6
Subtract 213 from both sides of the inequality:
10w + 213 - 213 ≥ 299 - 213
10w ≥ 86
Next, divide both sides of the inequality by 10 to solve for w:
10w/10 ≥ 86/10
w ≥ 8.6
Therefore, the correct answer is A. w ≥ 8.6
