Answer 1

To determine how many weeks it will take Ellie to save enough money for the phone, we can set up an inequality based on the information given.

Ellie currently has $213 saved, and she receives $10 a week in allowance. She wants to have at least $299 saved.

Let \( w \) represent the number of weeks. We can express the total amount of money Ellie will have after \( w \) weeks as:

\[ 10w + 213 \]

We want this amount to be at least $299, which gives us the inequality:

\[ 10w + 213 \geq 299 \]

So, the correct inequality that can be used to solve the problem is:

10w + 213 ≥ 299, where w is the number of weeks.
