\(\frac{(Difference)}{(Original)}*100 = \frac{(12.95 - 9.95)}{12.95}*100 = \frac{3}{12.95}*100\).

If it were 3/12*100, it would be 25% but since the denominator is larger than 12, the actual percentage is less.

Answer: E.

Change/Original x 100= 12.95-9.95/12.95

= 300/12.95

12.95x20 = 259. => approx 40 less than 300 => approx 3 more. therefore 300/12.95 is approx =23. Option (E)

The discount on the CD is 3$

The percent discount is (3/12.95)*100 = 30000/1295
~ 300/13 or 23%(Option E)

I would round up the numbers from 12.95 to 13 and from 9.95 to 10.
Hence, 13-10/13 = 23%

To calculate the percent decrease in price, we need to find the difference between the original price and the sale price, and then express that difference as a percentage of the original price.

Original price: $12.95
Sale price: $9.95

Difference in price: $12.95 - $9.95 = $3.00

Now, let's calculate the percent decrease:
Percent decrease = (Difference / Original price) * 100

Percent decrease = ($3.00 / $12.95) * 100 ≈ 23.17%

Therefore, the percent decrease in price is closest to 23%, which corresponds to option (E) in the given choices.
