Sarah is saving money to buy a new laptop that costs $850. She currently has $250 saved and plans to save $30 per week from her part-time job. Which equation represents the number of weeks (w) it will take Sarah to save enough money for the laptop?
✓ Correct Answer: Option B
Sarah starts with $250. She adds $30 each week, represented as 30w. The total amount saved must equal the laptop cost of $850. Thus, 250 + 30w = 850.
