To calculate the final price of the laptop, we need to apply the discount and then add the sales tax. Let's go step by step:

1. Initial Price: $1,200

2. Discount: 15% of $1,200

   $\text{Discount} = 0.15 \times 1200 = 180$

   So, the price after discount is:

   $\text{Discounted Price} = 1200 - 180 = 1020$

3. Sales Tax: 7% of the discounted price

   $\text{Sales Tax} = 0.07 \times 1020 = 71.4$

4. Final Price: Add the sales tax to the discounted price:

   $\text{Final Price} = 1020 + 71.4 = 1091.4$

Thus, the final price of the laptop is $1,091.40.

Here are 5 related questions:

1. What would the final price be if the discount was 20% instead of 15%?
2. How much would the total sales tax amount be without any discount?
3. If the discount was reduced to 10%, what would the final price be?
4. What if the sales tax was 10% instead of 7%—what would the final price be?
5. What is the percentage reduction in the original price after applying both the discount and tax?

Tip: To quickly calculate discounts, multiply the price by the percentage as a decimal (e.g., 15% = 0.15).
