This is actually quite simple to do. Instead of taking 5 percent, 20 percent, and 45 percent on, reverse the action by adding 5 percent, 20 percent, and 45 percent to the value.
50 * (1.05) * (1.20) * (1.45)
You'll have your answer.
50%
The discount value is $11.99 and the sale price is $67.99
$35.71
The regular price of an item is the non-sale price of that item.
The sale price is 12.15
-- subtract the percent off from 100 -- divide the sale price by the answer -- multiply that answer by 100, and you have the original price
$100.39
You'll save $14.85 on this item. This means, the cost of the item to you is: $99.00 - $14.85 = $84.15
13.77 will be the discounted price if the standard price is 16.50.
c = 1.0825p
The sale price would be $111.00 + tax.
To calculate it you multiply your cost by 0.94 If the cost is $100, then the price is $94
