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 levels of creatinine and BUN. Te normal range for creatinine in the blood may be 0.6 to 1.3 milligrams per deciliter (53 to 115 micromoles per liter), although this can vary from lab to lab, between men and women, and by age. Since men usually have high larger muscle mass, the amount of creatinine in the blood is often higher than women. In general,the normal BUN level ranges from 7 to 20mg/dL(2.5 to 7.1mmol/L).However, the normal BUN levels may vary with the lab, and your age.
