Answer 2

Calculating the Percentage Difference

To calculate the percentage by which the shirt is cheaper than the jacket, we can use the following formula:

Percentage Difference = ((Jacket Price - Shirt Price) / Jacket Price) * 100

Given that the jacket is 4 times more expensive than the shirt, we can represent the jacket price as "4x" and the shirt price as "x".

Substituting these values into the formula, we get:

Percentage Difference = ((4x - x) / 4x) * 100

Simplifying this expression, we find:

Percentage Difference = ((3x) / 4x) * 100

Percentage Difference = (3 / 4) * 100

Percentage Difference = 75%

Therefore, the shirt is 75% cheaper than the jacket.
