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)
A: w≥51.2
B: w≥860
C: w≥8.6
D: w≥86
C: w≥8.6

To solve the inequality, we need to isolate the variable 'w' on one side of the equation.
The inequality is given as: 10w + 213 ≥ 299.
First, subtract 213 from both sides of the equation: 10w ≥ 299 - 213.
Simplifying further, we have: 10w ≥ 86.
Finally, divide both sides of the equation by 10 to solve for 'w': w ≥ 8.6.
So, the correct solution is option C: w ≥ 8.6.
This means that after at least 8.6 weeks (or rounded up to 9 weeks), Ellie will have enough money saved to buy the phone.
