Question: 1) Alex has preferences represented by the utility function U(x, y) = 10x + 5y . She consumes 10 units of good x and 9 units of good y.

Question:1) Alex has preferences represented by the utility function

U(x, y) = 10x + 5y

. She consumes 10 units of good x and 9 units of good y. 

a.

Graph her indifference curve and indicate where this bundle would be on that indifference curve. 

b.

If her consumption of good x is lowered to 1, calculate how many units of y she must have in order to be exactly as well off as before.

c.

Suppose her utility function was U(x, y) = 10x5y. 

Does your answer to 2b change or remain the 

same? Explain why.
