Question

Terrance used this expression to find the final price, in dollars, of a hat that is discounted 30% off the original price of $20.


20-(20x0.3)

Answer 1

Terrance's expression, \(20 - (20 \times 0.3)\), is a way to calculate the final price of the hat after applying a 30% discount to the original price of $20.

Here's a step-by-step breakdown:

1. Calculate the discount amount:
\[
20 \times 0.3 = 6
\]

2. Subtract the discount from the original price:
\[
20 - 6 = 14
\]

So, the final price of the hat after the 30% discount is **$14**.

Alternatively, a more straightforward expression to calculate the final price directly after the discount would be:
\[
20 \times (1 - 0.3) = 20 \times 0.7 = 14
\]

Both methods result in the same final price of **$14**.
