Example Input: This mix allowed my little one to have cupcakes at his second birthday party. They turned out great and with some homemade vanilla icing, they were a hit with everyone! I even used Ener G's egg replacer to replace the multiple eggs the mix calls for. One hint, bake for almost the maximum time on the directions. They come out golden brown and moist.
Example Output: 5

Example Input: Good quality nectar. Very tasty. However, I was expecting 46 fluid ounces, not 46 ounces in weight. I find that 46 ounces in weight makes about 32 fluid ounces.
Example Output: 4

Example Input: I'm a bit perplexed wondering what void in the beverage market this is intended to fill. Imagine a super sweet slightly carbonated juice drink with an almost syrupy consistency and you have The Switch. I had to drink a tall glass of water after drinking a can of this carbonated candy in a can because it's anything but refreshing.
Example Output:
