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

Question

This is a problem from a 7th grade math test please help.

Answer 1

To find the percent increase in Dallas's wage, you divide the difference between the new and the old wage with the old wage and you multiply by 100:

 

% increase = 100 * (new wage - old wage) / old wage

 

% increase = 100* (10.25 - 9) / 9

 

% increase = 100 * 1.25 / 9

 

% increase = 14 %
