Answer:

The price of the DVD has decreased by 20%.

Step-by-step explanation:

formula Percentage = (number you want to find the percentage for ÷ total) × 100

280 - 220 = 60

280 x 0.215 = 60.2

0.215 ≈ 0.2

0.2 x 100 = 20

The price of the DVD increased by 20% (I might be wrong as I hate these kinda questions but I'm pretty sure it's right)
