This is the price with a 20% off sale.
$90,40 = (100%-20%) = 80%
If you divide 80% with 5 it turns into 20%.
($90,40/4) = $22,60 = 20%
Then you multiply the 20% with 5 to get 100% = The original price.
($20,60*5) = $103 = 100%
You don’t have to use my tactic or the one the teacher says, use the one that works and is the most suitable for you!
