Dallas got a raise. His hourly wage was increased form $9 to $10.25? What was the percent increase in Dallas's wage to the nearest whole percent?

First: work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number

Then: divide the increase by the original number and multiply the answer by 100.

% increase = Increase : Original Number * 100.

Increase = $10.25 - $9

% increase = $1.25/$9 x 100

% increase=13.888888889

% increase = 14%
