The Word Game

Okay. This problem is so easy, a fourth grader could figure it out in less than 20 minutes. All it takes is a little algebra... Ha, ha, ha, ha, ha!!!

Assume the following:
dog=10
owl=32
elf=6
yellow=25
blue=17
flower=26

Also, assume that each letter in the word stands for one distinct number, and each word represents a string of numbers being multiplied (i.e. dog= dxoxg). Assume that all multiplication properties hold.
a.) what is y in terms of f?

b.) what is the value of r?

c.) what is the value of e?
