Answer:
$42
Step-by-step explanation:
Original price: $56
Discount: 25%
A discount of 25% means that the discount is 25% of the price of the item, so you need to subtract 25% of the price of the item from the original price of the item.
Let's find an expression for the amount of the discount.
25% of $56 = 25% * $56 = 0.25 * $56
The amount of discount is 0.25 * $56.
Now we subtract that amount form the original price of $56.
$56 - 0.25 * $56 = $56 - $14 = $42
