The discount rate at the store closing is found by comparing the original and discounted prices of an item. The rate is calculated to be 0.4 or 40%, so the correct answer is A. 40%.
The question involves determining the store's universal discount rate applied to all items during a store closing. To find it, we can compare the original price of an item to its discounted price. Looking at the first item with an original price of $22.50 and a discounted price of $13.50, we can calculate the discount rate (DR) using the formula:
DR = (Original Price - Discounted Price) / Original Price
By plugging in the values, we get:
DR = (22.50 - 13.50) / 22.50 = 9 / 22.50 = 0.4
So the discount rate is 0.4, which is 40% when expressed as a percentage. Therefore, the correct answer is A. 40%.
