Percentage Increase in Furniture Sales (2019 to 2020)
Sales Data (in millions)
| Category | 2019 | 2020 |
|---|---|---|
| Bookcases | 1.9 | 2.2 |
| Chairs | 6.2 | 7.0 |
| Furnishings | 2.05 | 2.1 |
| Tables | 4.4 | 4.5 |
Calculation
Total sales in 2019 = 1.9 + 6.2 + 2.05 + 4.4 = 14.55 million
Total sales in 2020 = 2.2 + 7.0 + 2.1 + 4.5 = 15.8 million
Percentage Increase = ((15.8 − 14.55) / 14.55) × 100
= (1.25 / 14.55) × 100
≈ 8.59%
