The original selling price of a shirt was $45.

marissa [1.9K]

Given:

The original selling price of a shirt was $45.

In a sale, the shirt is reduced to $32.50.

To find:

The percentage reduction.

Solution:

We know that,

$\text{Percentage reduction}=\dfrac{\text{Original value - Reduced value}}{\text{Original value}}\times 100$

$\text{Percentage reduction}=\dfrac{45-32.50}{45}\times 100$

$\text{Percentage reduction}=\dfrac{12.50}{45}\times 100$

On further simplification, we get

$\text{Percentage reduction}=\dfrac{1250}{45}$

$\text{Percentage reduction}=27.777778$

$\text{Percentage reduction}\approx 27.78$

Therefore, the percentage reduction is 27.78%.
