Initial blood cholesterol level = 228 mg/dL

Blood cholesterol level after two months = 210 mg/dL

Formula used:

Decrease percentage is given by,

Decrease% = Decarease in valueOriginal value×100

Calculation:

Decrease percentage is calculated as:

Decrease% = Decarease in valueOriginal value×100      =228 mg/dL210 mg/dL228 mg/dL×100      =18 mg/dL228 mg/dL×100      =7.89%

Conclusion:

The patient cholesterol level decreases by 7.89%_ .
