Solutions to the second round of homework

[elblasco]

Here are my proposed solutions to the second homework.
I have a question about the second point of homework 2.2, file elblasco_hw_221.py, I only partially understood the second constraint:

2. The five butterflies were Nick's purchase, the butterfly that sold for $45 the peacock butterfly, the butterfly that sold for $90 and the butterfly that sold for $105.

The peacock butterfly has not been sold for 45$, 90$ or 105$, but I cannot understand the rest of the phrase, so I did not manage to encode it.

Thanks in advance for your feedback.

Correct, well done 🚀

Thanks for the explanation in the third homework. I have also tried to check the proposed model against all the constraints and it looks acceptable (to me).

I have lost access to the online riddle too :-(

Just minor comments, good job!

[masinag]

probably you can just say

Suggested change

	And(wvars["60linda"], Not(linda_bought_grayling)),
	And(wvars["60linda"], Not(bvars["60grayling"])),

Seems good to me 🚀
