Last Year Boris paid £256 for his car insurance This year he has to pay £894 for his car insurance Work out the percentage increase in the cost of his car insurance

%∆C = 249.22%

the percentage increase in the cost of his car insurance is 249.22%

Step-by-step explanation:

Given;

Cost of car insurance last year C1 = £256

Cost of car insurance this year C2 = £894

Percentage increase = change in cost/initial cost × 100%

%∆C = ∆C/C1 × 100%

%∆C = (C2-C1)/C1 × 100%

Substituting the given values;

%∆C = (894-256)/256 × 100%

%∆C = 249.21875%

%∆C = 249.22%

the percentage increase in the cost of his car insurance is 249.22%
