Ellie is saving to buy a phone. She wants to have at least $299 saved before buying one. She currently has $213 saved, and she receives $10 a week as an allowance from her parents. After how many weeks will Ellie have enough money saved? Ellie writes the inequality 10w + 213 > 299, where w is the number of weeks, to help figure this out. Solve her inequality. (1 point)
To solve the inequality, we need to isolate the variable w.
10w + 213 > 299
Subtract 213 from both sides:
10w > 86
Divide both sides by 10:
w > 8.6
Since w represents the number of weeks, Ellie will have enough money saved after 9 weeks because it takes more than 8.6 weeks to have enough money.
Answer: \boxed{9}.
