X+y<=20 is false, because it tries to correlate the amount of hats and scarfs with the time, without considering the time to knit each object

x<=5 is correct, he can at most make 5 hats for more he is missing yarn

y<=8 is correct, same reasoning but with scarfs

5x+8y<=20 is false, it compares the yarn requirements with the total time

12x+6y<=20 is correct, a corrected version of the first constraint which uses the worktime of each object essentially meaning "the time worked on all objects has to be less than the 20 hour time total"


so
x<=5
y<=8
12x+6y<=20
are correct

yanalaym [24]
Well we know that every 2 eggs requir 1 and 3/4 of flour so the easiest thing to do here (for me at least) is to round the fraction to the nearest whole number which in this case will be 1. Now that that's done we can say every 2 eggs calls for 2 cups of flour. Now all you need to do is multiply 2 by 9 to get 18 then put that in fraction form it'll be 17 and 3/4 cups of flour. I hope this helps!
