Final answer:
Mrs. Smith's shirt, originally priced at $32.99, has a 30% off sale, resulting in a sale price of $23.09 after calculating the discount and subtracting it from the original price.
Step-by-step explanation:
The sale price of the shirt Mrs. Smith found at Macy's with an original price of $32.99 and a discount of 30% can be calculated as follows:
- Calculate the amount of discount by multiplying the original price by the discount percentage (converted to decimal form).
- Subtract the discount amount from the original price to find the sale price.
Calculating the discount: $32.99 × 0.30 = $9.897
Subtracting the discount from the original price: $32.99 - $9.897 = $23.09 (rounded to the nearest cent).
Therefore, the direct answer to the question is that the sale price of the shirt is $23.09, which corresponds to option (a).
