Johnโs utility function is given by the following equation
๐(๐ฅ, ๐ฆ) = min(2๐ฅ, 5๐ฆ),
where x is the unit of good X consumed, and y is the unit of good Y consumed. Johnโs budget is $140, price of good X (๐๐) is $3, and price of good Y (๐๐) is $10. Show all the steps, with definition of every new notation used in the steps.
a) What is Johnโs optimal consumption (๐ฅ โ , ๐ฆ โ )? Graph the optimal consumption along with appropriate budget line and indifference curve.
b) If ๐๐ decreases from $3 to $2, what is the new optimal consumption (๐ฅ๐น, ๐ฆ๐น)? Graph the new optimal consumption along with appropriate budget line and indifference curve on part a)โs graph.
