The graph flattens when it is at a constant rate. Since a oven is heated energy it can’t be in the negatives or be zero because it has to be at a certain temperature to be considered ‘hot’.
U=200
n(G)=120
n(F)=100
n(GnF)=x
U=n(G)+n(F)-n(GnF)
200=120+100-x
x=20
French but not German is 100-20=80
percentage = 80/200 *100%= 40%
