An instrument used to measure cholesterol values has a certain range of values that it can measure. One patient's cholesterol value was too high, and the instrument could not read the value correctly. Therefore, the patient's cholesterol specimen was diluted as follows: 25 mL serum was added to 25 mL diluent. This diluted sample was then reanalyzed, and its cholesterol value was found to be 200 mg/dL. What dilution was performed, and what cholesterol value should be reported as the patient's actual cholesterol value?

What will be an ideal response?
