Explanation
Find Airline B's rating for convenience (8.0) and Airline A's rating for convenience (5.1).
Determine the increase: 8.0 – 5.1 = 2.9
Now we find the percent change and round to the nearest whole number: Percent change = increase ÷ original number × 100 → 2.9 ÷ 5.1 × 100 = 56.86% or 57%.
Hence option D is correct.
Find Airline B's rating for convenience (8.0) and Airline A's rating for convenience (5.1).
| Category | A | B | C |
| Convenience | 5.1 | 8.0 | 4.3 |
| Friendliness | 5.0 | 5.5 | 5.4 |
| Price | 5.0 | 6.4 | 3.5 |
| Promptness | 6.5 | 6.9 | 4.1 |
| Reliability | 7.8 | 7.5 | 4.9 |
| Total: | 29.4 | 34.3 | 22.2 |
Determine the increase: 8.0 – 5.1 = 2.9
Now we find the percent change and round to the nearest whole number: Percent change = increase ÷ original number × 100 → 2.9 ÷ 5.1 × 100 = 56.86% or 57%.
Hence option D is correct.
