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.
Blood urea nitrogen to creatinine ratio (BUN:creatinine) A BUN test may be done with a blood creatinine test. The level of creatinine in your blood also tells how well your kidneys are workingâa high creatinine level may mean your kidneys are not working properly. Blood urea nitrogen (BUN) and creatinine tests can be used together to find the BUN-to-creatinine ratio (BUN:creatinine). A BUN-to-creatinine ratio can help your doctor check for problems, such as dehydration, that may cause abnormal BUN and creatinine levels.
