The function is obviously a perfect complements function.
C = Cookery programs
I = Income
Pw = Price of wine
Pc = Price of cookery programs
To find the optimal choice you need to impose:
2W = C
Now, let's substitute intmato the budget line:
Pw*W+Pc*2W = I
W (Pw+2Pc) = I
W = I/ (Pw+2Pc)
This shows that the demand of W is inversely proportional to Pw, moreover watching cookery programs usually costs nothing.
If it costs nothing, the demand of wine is: W = I / Pw, which should suggest that the demand increases as Pw diminishes.
PS: Check the mathematical steps, I'm not too good at it and I could have made errors...
