During its first year, there were 138 volunteers at a community outreach program. Over the next 2 years, there were 156 volunteers and 175 volunteers, respectively. What is the percent of increase in volunteers from Year 1 to Year 2 and from Year 1 to Year 3? Round to the nearest tenth percent if necessary.

0.1%

Step-by-step explanation:

138 into a percent=1.38%

156 into a percent=1.56%

175 into a percent=1.75%

1.38-1.56=0.18

1.56-1.75=0.19

0.19-0.18= 0.1%
