Final answer:
To find the discounted price of a $100 shirt with a 40% discount, multiply $100 by 0.40 to calculate the discount amount, which is $40. Subtract this from the original price to get the final price: $100 - $40 = $60.
Step-by-step explanation:
The question is asking for the final price of a shirt after applying a discount. To solve this problem, we must first determine the amount of the discount by calculating 40% of the original $100 price. We do this by multiplying the original price by the percentage of the discount in decimal form, which is 0.40.
$100 × 0.40 = $40
This result represents the discount amount. The next step is to subtract the discount from the original price:
$100 - $40 = $60
Therefore, the price of the shirt after a 40% discount is $60. The correct answer is A) $60.
