Final answer:
To find the sale price after a 25% markdown on a $12.99 item, first calculate the markdown amount by multiplying 12.99 by 0.25. Then subtract the markdown amount from the original price to get the sale price.
Step-by-step explanation:
To find the markdown amount, first, we need to calculate 25% of the original price. Given that the original price is $12.99:
Calculate 25% of $12.99: 12.99 * 0.25 = $3.2475
The markdown amount is $3.2475.
To find the sale price, subtract the markdown amount from the original price:
Subtract $3.2475 from $12.99: $12.99 - $3.2475 = $9.7425
The sale price after a 25% markdown is $9.7425.
