Answer: You will pay $629.30 for the pair of shoes after the 30% discount is applied.
Explanation:
If Supershoes is offering a 30% discount on the marked price of all sports shoes, and a pair of shoes is marked at $899, then the discount on the shoes will be:
Discount = 30% of $899
Discount = 0.3 * $899
Discount = $269.70
The discount of $269.70 is subtracted from the marked price of the shoes to get the discounted price that you will pay:
Discounted price = Marked price - Discount
Discounted price = $899 - $269.70
Discounted price = $629.30
