Original price of a CD: $22.99
Discount:5%

Hi,

As I understand it, you want to know the value of the discounted CD, right?

The 5% discount value is $1.15 and the CD value with a discount $21.84.

This can be easily solved using the rule of three.

Step-by-step explanation:

First, let's consider that the full value of the CD represents 100%:

Value ($)                                     Percent (%)

22.99   ---------------------------------     100%

Next, we consider the discount amount to be "x":

Value ($)                                    Percent (%)

22.99   ---------------------------------     100

   x       ---------------------------------       5

Finally, we multiply in a cross:

Isolating the x:

Therefore, the 5% discount amount is $ 1.15.

To find the value of the CD with a 5% discount, just subtract:
