The total cost of 50 laptops that Bill bought last month = 50 * 400£ = 20,000£.
For the 40 laptops that he sold at a profit of 30%, his selling price for each laptop = 400£ + 30% of 400£ = 520£. The total revenue from selling these 40 laptops = 40 * 520£ = 20,800£.
For the 10 laptops that he sold at a profit of 15%, his selling price for each laptop = 400£ + 15% of 400£ = 460£. The total revenue from selling these 10 laptops = 10 * 460£ = 4,600£.
Therefore, the total revenue from selling all 50 laptops = 20,800£ + 4,600£ = 25,400£.
Since the total revenue from selling all 50 laptops exceeded Bill's target of at least 25,000£, we can conclude that Bill reached his target last month.
Let's calculate the profits and revenues from the sale of Bill's laptops. Profit from selling 40 laptops:
- Profit on each laptop = 30% of 400£ = 120£
- Total profit from selling 40 laptops = 120£ x 40 = 4,800£
- Revenue from selling 40 laptops = (400£ + 120£) x 40 = 20,800£ Profit from selling 10 laptops:
- Profit on each laptop = 15% of 400£ = 60£
- Total profit from selling 10 laptops = 60£ x 10 = 600£
- Revenue from selling 10 laptops = (400£ + 60£) x 10 = 4,600£ Total profit and revenue from selling all 50 laptops:
- Total profit = 4,800£ + 600£ = 5,400£
- Total revenue = 20,800£ + 4,600£ = 25,400£ Bill reached his target of selling all 50 laptops for a total of at least 25.000£.
