Based on the table below, what was the approximate percentage increase in total sales from 2021 to 2023?

✓ Correct Answer: Option C

Total sales in 2021 = $150,000 + $200,000 = $350,000. Total sales in 2023 = $180,000 + $270,000 = $450,000. Percentage increase = (($450,000 - $350,000) / $350,000) * 100% = ($100,000 / $350,000) * 100% = (2/7) * 100% ≈ 28.6%.
