Final answer:
The sale price after a 25% discount for sheets originally marked $12.50 is $9.38, and for pillow cases originally marked $4.50, it is $3.38.
Step-by-step explanation:
The student's question is about calculating the sale price of items (sheets and pillowcases) after applying a discount. To find the sale price, one must subtract the discount amount from the original price. The discount amount can be found by multiplying the original price by the discount percentage (25% in this case).
For sheets marked at $12.50:
- Calculate the discount amount: $12.50 × 25% = $3.125.
- Subtract the discount from the original price: $12.50 - $3.125 = $9.375 (or $9.38 if we round to the nearest cent).
For pillow cases marked at $4.50:
- Calculate the discount amount: $4.50 × 25% = $1.125.
- Subtract the discount from the original price: $4.50 - $1.125 = $3.375 (or $3.38 if we round to the nearest cent).
Therefore, the sale price for the sheets is $9.38, and for the pillow cases, it is $3.38 after a 25% discount.
