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.
Normal creatinine clearance for men is between 97 to 137 milliliters per minute, and women have a normal clearance of 88 to 128 milliliters per minute. BUN/creatinine is the ratio between blood urea nitrogen (BUN), a waste product in the blood from protein metabolism, and creatinine.ormal creatinine clearance for men is between 97 to 137 milliliters per minute, and women have a normal clearance of 88 to 128 milliliters per minute.
