Final answer:
The sale price of a computer originally priced at $843.75 after a 40% markdown is $506.25.
Step-by-step explanation:
To calculate the sale price of a computer after a markdown, we need to find the discount amount and subtract it from the original price. The computer is originally priced at $843.75, and the markdown is 40%. First, we calculate the discount amount by multiplying the original price by the discount percentage:
Discount Amount = Original Price × Discount Percentage
Discount Amount = $843.75 × 0.40 = $337.50
Next, we subtract the discount amount from the original price to find the sale price:
Sale Price = Original Price - Discount Amount
Sale Price = $843.75 - $337.50 = $506.25
Therefore, the sale price of the computer after a 40% markdown is $506.25.
