C. The same as one 36 percent discount
D. The same as one 30 percent discount
E. The same as one 25 percent discount

Let's start with a nice number

Let $100 be the ORIGINAL price.
So, a 20% discount on $100 = $20, which means the discounted price = $100 - $20 = $80

Next, a 20% discount on $80 = $16, which means the NEW discounted price = $80- $16 = $64

So, if the ORIGINAL price = $100, the DOUBLE DISCOUNTED price = $64
In other words, the DOUBLE DISCOUNTED price is $36 less than the ORIGINAL PRICE

This represents an overall discount of 36%

Answer: C
