Question: Floor tiles cost £4.25 each.
Work out the total cost of 35 tiles.
1. **State the problem:** We need to find the total cost of buying 35 floor tiles, each costing 4.25.
2. **Formula used:** Total cost = Number of tiles \( \times \) Cost per tile
3. **Apply the formula:**
$$\text{Total cost} = 35 \times 4.25$$
4. **Calculate the multiplication:**
$$35 \times 4.25 = 35 \times \left(4 + 0.25\right) = 35 \times 4 + 35 \times 0.25$$
$$= 140 + 8.75 = 148.75$$
5. **Conclusion:** The total cost for 35 tiles is 148.75.
