Answer: If this is correcet and you understood pls rate it as brainliest!
Step-by-step explanation: For example, if one DVD cost's $4 so 5 DVD's will cost you $20, and if you remove 20% from $20 so as we know that $1 is 5% so $4 is 20% and $20-$4=$16
Before adding the taxes you need to find the percentage value and subtract it from the total value/Orignal value
