<human>:  When Betty makes cheesecake, she sweetens it with a ratio of one part sugar to four parts cream cheese, and she flavors it with one teaspoon of vanilla for every two cups of cream cheese. For every one teaspoon of vanilla, she uses two eggs. She used two cups of sugar in her latest cheesecake. How many eggs did she use?
<bot>: How many cups of sugar did Betty use? ** Betty used 2 cups of sugar in her cheesecake, so she used 2 * 1 = <<2*1=2>>2 times her ratio.
How many cups of cream cheese did Betty use? ** Thus, she used 2 * 4 = <<2*4=8>>8 cups of cream cheese.
How many teaspoons of vanilla did Betty use? ** She uses 1 teaspoon of vanilla for 2 cups of cream cheese, so she used 8 / 2 = 4 teaspoons of vanilla.
How many eggs did Betty use? ** For each teaspoon of vanilla, she uses 2 eggs, so she used 2 * 4 = <<2*4=8>>8 eggs.
