Question: 1 / 400

What is the new price of a shirt that costs $20 if the price is increased by 15%?

$21

$23

To determine the new price of a shirt after a 15% increase on its original price of $20, you first need to calculate the amount of the increase. This is done by multiplying the original price by the percentage increase, in decimal form.

First, convert 15% to a decimal by dividing by 100:

15% = 0.15.

Next, calculate the amount of the increase:

Increase = Original Price × Percentage Increase

Increase = $20 × 0.15

Increase = $3.

Now, add this increase to the original price to find the new price:

New Price = Original Price + Increase

New Price = $20 + $3

New Price = $23.

Thus, the new price of the shirt after a 15% increase is $23. This calculation effectively reflects how percentage increases are applied to a base price, reinforcing the understanding of percentage operations in real-world financial scenarios.
