A store discounted items by 50% off the original price one week. The following week and additional 10% was taken off the already reduced price. The regular price of a CD player is $85.00. What is the reduced price in the second week?
First we find 50% of $85.00 and subtract it from the original price.
50% is 42.50. We take that away from the original price because it's the discount.
So the selling price for the first week is $42.50
$42.50 is now our new 100%. We now have to find 10% discount of that. Instead of finding 10% and subtracting it from the total, a shorter way is to just find 90%. Because 100% take away 10% equals 90%. Using this method, you will be able to skip one step which is subtracting. This will also save you time.
The selling price after the second week is $38.28
