Question

your last doctors visit cost $105. health insurance through your employer paid $84, and you paid the remaining $21. what percentage of the cost did you pay?
20%
21%
25%
80%
84%

Explanation:

Step1: Recall percentage formula

The formula for percentage is $\text{Percentage}=\frac{\text{Part}}{\text{Whole}}\times100\%$. Here, the part you paid is $21$ and the whole cost is $105$.

Step2: Substitute values into formula

$\text{Percentage}=\frac{21}{105}\times 100\%$. First, calculate $\frac{21}{105}=\frac{1}{5}= 0.2$. Then, $0.2\times100\% = 20\%$.

Answer:

A. 20%
