Answer:

-18.18%

Explanation:

The percentage change is the ratio of the change in price divided by the initial price, it can be calculated by the formula below:

Percentage change = [tex]\frac{(Pn - Po)}{Po} * 100%[/tex]  

Where                  Pn = New price

                            Po = Initial or old price

                            Pn =  $18

                            Po = $22

Percentage change = {($18 - $22)/$22} * 100%

                                 = {($18 - $22)/$22} * 100%

                                 = {-$4/$22} * 100%

                                 = -0.1818181818 * 100%

                                 = -18.18181818%

                                 = -18.18%              (to two decimal places).  

The negative figure means they are complementary goods, that is goods that are consumed together.
