中级微观经济学选择,
Hans has 27 dollars,which he decides to spend on x and y.Commodity x costs $16 per unit and commodity y costs $10 per unit.He has the utility function U(x; y) = 5x^2 + 2y^2 and he can
purchase fractional units of x and y.
(a) Hans will choose only x.(b) Hans will choose only y.
(c) Hans will choose some of each commodity,but more y than x.(d) Hans will choose some of each commodity,but more x than y.
答案为什么选B?不是根据MUx/MUy=Px/Py做么?

我做了一下,选择c,并且,x的数量0.854,y的数量1.336,的时候效用最大
