Let's rewrite the information then figure out the answer. 

DVD: $9.00 originally but on sale with an 80% discount. 
80%=0.80
9.00(0.80) = $7.20
$9.00 - $7.20 = $1.80

Thus, the sales price is: $1.80

multiply $9 by 80%

80% = 0.80

9 * 0.8 = 7.20

 subtract that from original price

9 - 7.20 = 1.80

 Sale price is $1.80
