If a t-shirt goes on sale for 25% off, how much is the discount on a T-shirt that originally costs $36.00?

0.25 * 36 = ?

I got 9.00, is this correct Ms. Sue? :)

Yes.

To find the discount on a T-shirt that is now on sale for 25% off, you can follow these steps:

1. Calculate the discount amount by multiplying the original price of the T-shirt by the percentage discount.
Discount amount = Original price * Percentage discount

2. Substitute the given values into the formula.
Discount amount = $36.00 * 0.25

3. Perform the calculation.
Discount amount = $9.00

Therefore, the discount on the T-shirt is $9.00.
