The difference between MSRP sticker price (retail price) and invoice price (wholesale price) is a dealerâs potential profit margin, assuming vehicles sell at sticker price â ignoring other costs, charges, or rebates he might receive. This dollar margin, as a percentage of sticker price, is not the same on all vehicles.he difference between MSRP sticker price (retail price) and invoice price (wholesale price) is a dealerâs potential profit margin, assuming vehicles sell at sticker price â ignoring other costs, charges, or rebates he might receive.

In cases of dehydration, BUN may increase in a higher proportion than the creatinine. A normal BUN-to-creatinine ratio is between 10 to 1 and 20 to 1. (For example, a BUN of 14 and a creatinine of 1.2 would be a ratio of 12.) In cases of dehydration, the BUN-to-creatinine ratio may be higher than 20 to 1, as the kidney responds by making the urine more concentrated.
When your BUN levels are compared with your creatinine levels, it gives a fuller picture of whatâs happening with your kidneys. This is known as the BUN/Creatinine ratio. Creatinine is a waste product from your muscles that is also filtered by your kidneys. Like BUN, high levels of creatinine could mean there is a lot of waste product that hasnât been removed by the kidneys. The ideal ratio of BUN to creatinine falls between 10-to-1 and 20-to-1. Having a ratio above this range could mean you may not be getting enough blood flow to your kidneys, and could have conditions such as congestive heart failure, dehydration, or gastrointestinal bleeding.
