Answer:
B (2,1)
Step-by-step explanation:
The original price of an item at the store's President's Day sale, that's now reduced to $140 after a fifth off, would have been $175.
The subject of this question is mathematics, specifically applying percentages and fractions in context of a store sale. To solve this problem, you need to understand that a fifth off the original price means the sale price is 80% (or 4/5) of the original. If $140 is 80% of the original price, you can find the original price by dividing $140 by 0.8.
Here are the calculations:
Thus, the original price of the item at the President's Day sale was $175.
