[商管] [經濟]-消費者均衡探討
Janet consumers two commodities X and Y. Her utility function is
min{X+2Y, Y+2X}. She choose to buy 10 units of goods X and 20
units of good Y.The price of good X is 1. Which of the following is ture?
a. Icome is 40
b. Icome is 50
c. Icome is 30
d. Icome is 20
答案是D
解釋為 X=10<Y=20 → U=Y+2X →M=20
但是我還是看不懂
因為X<Y 所以選出了U=Y+2X 的效用函數但是如何求出所得的勒?
希望有高手可以替我解答?
