Quizplus · Accepted Answer

To find the percent increase, we can use the following formula: 
Percent increase = ((new value - old value)/old value) * 100%
Plugging in the values, we get: 
Percent increase = ((550 - 500)/500) * 100%
Percent increase = (50/500) * 100%
Percent increase = 0.1 * 100%
Percent increase = 10%
Therefore, the percent increase is 10%, which corresponds to answer choice B.
