Final answer:
The original cost price of the bed sheet is found by dividing the sale price of $483 by 1.15, resulting in a cost price of $420.
Step-by-step explanation:
To find the Cost Price of the bed sheet, we first understand that the bed sheet was sold at a 15% profit. This means that the sale price ($483) is 115% of the original cost price. To find the cost price, we can set up the equation:
Cost Price + 15% of Cost Price = Sale Price
115% of Cost Price = $483
To find the cost price, we divide the sale price by 1.15:
Cost Price = $483 / 1.15
Cost Price = $420
Therefore, the original cost price of the bed sheet was $420.
