Shana recently led efforts to clean up the city park for the kids and efforts to provide home and yard repair or cleaning for individuals who needed assistance. Of the 80 volunteers who showed up to help with the city park clean-up one Saturday, 60% returned a second Saturday to help with the community outreach service day to the elderly or disabled. After this second Saturday, 6 of the volunteers signed up to continue helping with the community outreach service day once a month. What percentage of the volunteers from the second Saturday signed up to continue helping with community outreach service day once a month?

The total number of volunteers who showed up on the second Saturday was 80 * 0.6 = 48 volunteers.

Out of those 48 volunteers, 6 signed up to continue helping once a month.
Therefore, the percentage of volunteers from the second Saturday who signed up to continue helping once a month is 6 / 48 * 100% = 12.5%.
