A manager's operation had sales this period of $89,775. last period sales were $85,500. So the manager's percentage sales increase for this period when compared to last period was 5% .
The percentage increase is the measure of the percentage change. The percentage increase is defined as the ratio of increased value to the original value and then multiplied by 100. Here the increased value can be calculated by taking the difference between the final value and the initial value. The formula to calculate increase is given by -
Percentage Increase = [(Final value – Original value) × 100] / Original value %
In this case, original value is $85500 and the final value is $89775, then the percentage increase is:
Percentage Increase = [(89775-85500) ×100]/85500
= 427500/85500
= 5%
So, the percentage increase will be 5% .
