Question

The average cost for a gallon of gasoline increased from $2.56 one year to $3.18 the next year. What is the percent of increase, rounded to the nearest whole number?

Answer 1

%change=100(final-initial)/initial

In this case:

%change=100(3.18-2.56)/2.56

%change=100(0.62)/2.56

%change=62/2.56

%change=775/32%

%change=24.21875%

%change≈24%  (to nearest whole percent)

Answer 2

Answer:

The answer is 24% Hopefully this helps!
