First find the total number of cranberries harvested by humans: 60000 cranberries * 40% = <<60000*40*.01=24000>>24000
Then subtract the number of cranberries taken by the humans and elk to find the number remaining: 60000 cranberries - 24000 cranberries - 20000 cranberries = <<60000-24000-20000=16000>>16000 cranberries
#### 16000
