The amount after the discount would be:
45 dollars - 11.25 dollars = 33.75 dollars.

Discount = 15 dollars * 10% = 0.10 * 15 = 1.50 dollars
The amount after the discount would be:
15 dollars - 1.50 dollars = 13.50 dollars.
To calculate the price of a $30 item with a 15% discount, follow these steps:
1. Start by converting the discount percentage to decimal form. Divide the percentage by 100. In this case, 15% becomes 0.15.
2. Multiply the original price of the item by the decimal value obtained from step 1. For a $30 item, 0.15 multiplied by $30 gives you $4.50.
3. Subtract the calculated amount from the original price of the item to get the discounted price. In this case, $30 minus $4.50 gives you $25.50.
Therefore, after applying a 15% discount, the price of the $30 item would be $25.50.
