Heres the problem:

Question

Winchester's local toy store sells items according to its own pricing system. A doll costs $10, a toy train costs $20, a cradle costs $20, a jumping jack costs $30, and a Tickle Me Elmo costs $50. Using the same system, how much does a drum cost?

I know the answer is $10,but I HAVE to explain why. Any patterns you see?

Answer 1

One pattern that I see is the number of letters in the toy name. The pattern is not absolutely linear. But regardless, the more expensive the toy the longer the name.

Answer 2

Thank you economyst! Well I figured out it's actually the amount of syllables (10)! (doll, toy-train, crad-le, jump-ing-jack, tick-le-me-elmo, drum)
