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)

Question

w≥51.2

w≥860

w≥8.6

w≥86

Answer 1

To solve the inequality, begin by isolating the variable w by subtracting 213 from both sides:
10w + 213 - 213 ≥ 299 - 213
10w ≥ 86.

Then, divide both sides of the inequality by 10:
10w/10 ≥ 86/10
w ≥ 8.6.

Therefore, the solution to the inequality is w ≥ 8.6.
