Final answer:
To find the original price of the jeans, use the formula Original Price = Sale Price / (1 - Discount Percentage). In this case, the original price is $31.25.
Step-by-step explanation:
To find the original price of the jeans, we need to determine the amount of the discount and then calculate the original price using the formula:
Original Price = Sale Price / (1 - Discount Percentage)
In this case, the jeans are sold for $25 and the discount is 20% of the original price. To find the discount amount, we multiply the original price by the discount percentage:
Discount Amount = Original Price * Discount Percentage
Substituting the given values:
Discount Amount = $25 * 0.20 = $5
Now, we can calculate the original price:
Original Price = $25 / (1 - 0.20) = $25 / 0.80 = $31.25
