Original price: $29.99; Markdown; 33 and 1/3%
Jobisdone [24]
If your asking what the price of something is, that was originally 29.99, and has been marked down by 33.33%, the easy way to do this is to take 30 and multiply it by 1/3, resulting in 20. The proper way is to take your calculator and multiply 29.99 by 0.333, resulting in roughly 9.98, meaning the price you pay is 20.00. Either way, your still going to pay $20 for the item.
