Laptop computers are popular all over the world. People use them on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classroom.
Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a $10 million computer program at Westlake, a 100-year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use email to "speak" with their teachers, their classmates, and their families. However, the most important 'part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast food restaurant or under the trees- anywhere at all!
Because of many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only the Internet, but also libraries and other resources. State higher education officials are studying how laptops can help students. State officials are also testing laptop programs at-other universities, too.
At Westlake College, more than 60 percent of the staff use computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, "Here we are in the middle of Virginia and we're giving students a window on the world. They can see everything and do everything."

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£.
