Percentage Increase in Health Screenings

A regional health organization is analyzing the number of health screenings conducted in several communities over the past year. The data collected, in thousands of screenings, is listed below:

• Community A: 5
• Community B: 7
• Community C: 12
• Community D: 10

To evaluate the effectiveness of health promotion efforts, the organization wants to determine the percentage increase in health screenings from Community A to Community C.

To find this percentage increase, use the formula:

$$ ext{Percentage Increase} = rac{ ext{New Value} - ext{Old Value}}{ ext{Old Value}} imes 100$$
