Final answer:
To find the new price of the jacket with a 30% discount, convert 30% to a decimal (0.30), multiply it by the original price ($20), and subtract the result from the original price. The new price is $14.
Step-by-step explanation:
The question involves calculating the new price of an item after applying a discount—which is a basic mathematics problem often taught at the middle school level. To find the new price, we need to calculate 30% of the original price and then subtract that amount from the original price. Here is how you can calculate the new price:
- Convert the percentage to a decimal: 30% = 0.30.
- Multiply the original price by the decimal: $20 × 0.30 = $6.
- Subtract the discount from the original price: $20 - $6 = $14.
Therefore, the new price of the jacket, after a 30% discount, is $14.
