Answer 1

To determine how many weeks it will take for Ellie to have at least $299 saved, we can set up the following inequality:

Ellie's current savings: $213
Amount she receives per week: $10
Target savings: $299

After \( w \) weeks, Ellie's total savings would be:
\[ 213 + 10w \]

We want this amount to be at least $299, so we set up the inequality:
\[ 213 + 10w \geq 299 \]

This corresponds to the option:
10w + 213 ≥ 299, where w is the number of weeks.
