Sagot :

Answer:

Percentage change = 26.61 %

Step-by-step explanation:

Given

  • Initial value = £78.98
  • Final value = £100​

To determin

Percentage change = ?

Using the formula

Percentage change = (Final value - Initial value) / | Initial Vaue |  × 100%

                                  = (100​ - 78.98) / 78.98  × 100%

                                  = [21.02/78.98] × 100%

                                  = 0.266143 × 100%

                                  = 26.6143 %

Rounding off to 2 decimal places

                                   = 26.61 %

Therefore,    

Percentage change = 26.61 %
