The reduced insurance cost  is £685.42.

Step-by-step explanation:

The amount paid per year for insurance = £714.73

Now the price is reduced by  4.1%

Calculating  4.1% of the  amount £ 714.73, we get:

4.1% of 714.73   =  

⇒4.1% of £ 714.73  = £29.30

So, the reduced insurance amount =   £ 714.73  -  £29.30

                                                                        = £685.42

Hence, the reduced insurance cost  is £685.42.
