🤖 Ai回答: 要确定电脑主机卖了值多少钱,我们需要 know the original price of the computer and the percentage or amount of discount applied、Since the problem does not provide specific details about the original price or the discount, I will assume we have the necessary information to proceed with a general solution.
Let's denote the original price of the computer as \( P \) and the discount percentage as \( D \)、The discount amount can be calculated as:
\[ \text{Discount Amount} = P \times \frac{D}{100} \]
The selling price of the computer after the discount is:
\[ \text{Selling Price} = P \text{Discount Amount} = P P \times \frac{D}{100} = P \left(1 \frac{D}{100}\right) \]
If we had specific values for \( P \) and \( D \), we could substitute them into this formula to find the selling price、For example, if the original price \( P \) was $1000 and the discount percentage \( D \) was 20%, the selling price would be:
