Answer

Explanation:

Step1: Recall average formula

Average = $\frac{\text{Sum of values}}{\text{Number of values}}$. Here number of values is 4 (4 quarters).

Step2: Estimate Amanda's revenue

From the bar - chart, Amanda's revenues (in thousands) seem to be approximately 50, 40, 80, 30. Sum = $50 + 40+80 + 30=200$. Average = $\frac{200}{4}=50$.

Step3: Estimate Brendon's revenue

Brendon's revenues (in thousands) seem to be approximately 70, 60, 50, 40. Sum = $70 + 60+50 + 40 = 220$. Average = $\frac{220}{4}=55$.

Step4: Estimate Cathy's revenue

Cathy's revenues (in thousands) seem to be approximately 60, 30, 20, 70. Sum = $60+30 + 20+70 = 180$. Average = $\frac{180}{4}=45$.

Answer:

A. Amanda made an average revenue of $50,000 over the four quarters of 2016.
