Final answer:
Without specific numerical values for the original sale change, we cannot calculate the exact savings from the coupon. However, the coupon would provide an additional 25% off of the already reduced sale amount. Any resulting figures involving cents would be rounded to the nearest penny.
Step-by-step explanation:
To determine the total change in the price of a pair of jeans after the sale and coupon, we need to use the information provided. However, it seems there is a piece of information or numerical values missing regarding the original sale change to accurately calculate the reduction after applying the coupon. Without this specific information, we cannot compute the exact saving or new price.
To assist, given a hypothetical scenario where the sale reduces the price of the jeans by a certain percent or dollar amount, the coupon would provide an additional 25% off of the reduced sale amount. For example, if the jeans went on sale and the price was reduced by $10, the coupon would take an additional 25% off the $10, which is $2.50 (0.25 x $10). The total savings would thus be $10 + $2.50 = $12.50.
In cases where rounding is necessary, such as when dealing with cents, we round to the nearest penny. For example, if after the application of the coupon the saving amount was $6.375, we would round it to $6.38, the nearest cent.
