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.
BUN levels increase with age. BUN levels in very young babies are about 2/3 of the levels found in healthy young adults, while levels in adults over 60 years of age are slightly higher than younger adults. What is a BUN/Creatinine ratio?
