Gorkem wants to buy a computer that costs \( £ 449.50 \) He already has \( £ 135 \) He will save \( £ 18.50 \) each week. In how many weeks will he have saved enough?

To determine how many weeks Gorkem needs to save to afford the computer, let's break down the problem step by step. ### Given: - **Cost of the computer:** £449.50 - **Current savings:** £135 - **Weekly savings:** £18.50 ### Goal: Find the number of weeks (**w**) required for Gorkem's total savings to reach or exceed £449.50. ### Calculation: 1. **Determine the remaining amount to save:** \[ \text{Remaining Amount} = \text{Cost of Computer} - \text{Current Savings} = £449.50 - £135 = £314.50 \] 2. **Calculate the number of weeks needed:** \[ \text{Number of Weeks} = \frac{\text{Remaining Amount}}{\text{Weekly Savings}} = \frac{£314.50}{£18.50} = 17 \text{ weeks} \] - **Explanation:** - £18.50 × 17 weeks = £314.50 ### Conclusion: Gorkem will need to save for **17 weeks** to have enough money to purchase the computer.
