Chapter 23, Problem 49R

To determine

To calculate: Decrease in patient’s cholesterol level as a percentage.

Answer to Problem 49R

The patient cholesterol level decreases by $\underset{\_}{7.89\%}$ .

Explanation of Solution

Given:

Initial blood cholesterol level = $228\text{ mg/dL}$

Blood cholesterol level after two months = $210\text{ mg/dL}$

Formula used:

Decrease percentage is given by,

$\text{Decrease\% = }\frac{\text{Decarease in value}}{\text{Original value}}\times 100$

Calculation:

Decrease percentage is calculated as:

$\begin{array}{l}\text{Decrease\% = }\frac{\text{Decarease in value}}{\text{Original value}}\times 100\\ =\frac{228\text{ mg/dL}-210\text{ mg/dL}}{228\text{ mg/dL}}\times 100\\ =\frac{18\text{ mg/dL}}{228\text{ mg/dL}}\times 100\\ =7.89\%\end{array}$

Conclusion:

The patient cholesterol level decreases by $\underset{\_}{7.89\%}$ .
