First find the number of votes for the unicorn cake: 7 votes * 3 = <<7*3=21>>21 votes
Then find the number of votes for the dragon cake: 25 votes + 7 votes = <<25+7=32>>32 votes
Then add the number of votes for each cake to find the total number of votes: 21 votes + 32 votes + 7 votes = <<21+32+7=60>>60 votes
#### 60
