A company's quarterly sales (in thousands of dollars) for the year were: Q1: $120, Q2: $150, Q3: $180, Q4: $160. What was the company's average monthly sales for the entire year?

✓ Correct Answer: Option B

Total annual sales = $120 + $150 + $180 + $160 = $610 thousand. There are 12 months in a year. Average monthly sales = $610,000 / 12 = $50,833.33, which rounds to $50,833.
