I agree, its not a guessing game - I just wanted to give him some numbers close to the answer so he could understand that there is only one combination that can satisfy both since one of the prices is constant.

Using x= 1k, y=10k, z = 900:
.25x + 1y + .5z = 10700 (correct)
.35x + 1.5y + .5z = 15800 (off by $20)

How is that not close?
