(1) NS, we could have any number of German nutcrackers and the rest would just have to be cheap enough such that 10 cost 2050.

E.g. 3 german = 675, the other 7 must = 1375, or 5 german = 1125, the other 5 must = 925

and clearly 1375/7 doesn't equal 925/5

(2) 0.6*(225) + 0.4*(x) = 205, solve for x and it is sufficient, B

Should be B: Stat 1 gives us
2050=225g+NX (#of non-german times average)
2050/205= 10
g+n= 10 types
3 variables = non sufficient

2: .6*225+.4*x= 205
solve and there you have it
