Sam's is interested in two goods, X and Y. His indirect utility function is

U* = M px-0.8 py0.8-1.    ( same as U* = M /(px0.8 py1-0.8 )   )

where M is Sam's income, and  px   and py  denote respectively the price of good X and the price of good Y. 

Sam's market demand function for good X is X*=0.8M/px

Find the absolute value of the change in Sam's consumers surplus if the price of good X rises from 1 to 4 dollars due to a per-unit tax imposed by the government, assuming his income is M=514 and price of good Y is equal to 4.

Sam's is interested in two goods, X and Y. His indirect utility function is
