Anderson makes mud masks for spa treatments. In every batch of mud that he mixes, he adds three sprigs of mint, and he adds two green tea leaves for every sprig of mint. He had to switch to a different kind of mud, which makes the other ingredients he adds half as effective. How many green tea leaves should Anderson add to a new batch of mud to get the same efficacy as before?
Anderson adds 3 * 2 = <<3*2=6>>6 green tea leaves in every batch of mud.
They are half as effective in the new mud, so Anderson should ad 6 * 2 = <<6*2=12>>12 green tea leaves to get the same efficacy as before.
