Answer:
 The percentage change = 6.05%
Step-by-step explanation:
New value = £209.99
Old value = £198
Percentage change = [New Value - Old Value] / [Old Value] × 100
                                  = [209.99 - 198] / [198] × 100
                                  = [11.99] / [ 198] × 100
                                  = 0.06 × 100
                                  = 6.05%
Therefore, the percentage change = 6.05%
