To find the sale price of the laptop, you can use the following steps:

1. Calculate the discount amount:
   $\text{Discount} = 20\% \text{ of } 1200 = \frac{20}{100} \times 1200 = 0.2 \times 1200 = 240$

2. Subtract the discount from the original price:
   $\text{Sale Price} = 1200 - 240 = 960$

So, the sale price of the laptop is $960.

Would you like more details on how this is done, or do you have any other questions?

Here are 5 related questions for further practice:

1. What would the sale price be if the discount was 25% instead of 20%?
2. If the laptop was $1500 instead of $1200, what would the sale price be with a 20% discount?
3. How much would you pay if you had an additional 5% discount on the sale price?
4. If tax is 8%, what is the total price including tax after applying the discount?
5. How do you calculate the original price if you only know the sale price and the discount percentage?

Tip: When calculating percentages, converting the percentage to a decimal (like 20% to 0.20) makes the multiplication easier.
